A variety of forming methods can be utilized to achieve opti-mum performance. Bellows can be selected or designed for any application or market. Single or multi-ply fabrication capabilities allow for a wide range of pressure, cycle life, or spring rate requirements.Flex-Weld, Inc.’s exceptional manufacturing methods result in a bellows configuration that exceed each industry’s highest standards. Uniform wall thickness, symmetrical convolu-tions and reliable spring rates are assured. All incoming material is metallurgically checked to internal requirements. Our proprietary forming processes preserve and in-crease the inherent strength and ductility of the bellows material to enhance cycle life and fatigue resistance.The most important feature of Flex-Weld bellows is the multi-ply geometry produced by telescoping thin wall precision tubing. Utilizing the same dimensions, Flex-Weld bellows can accept significantly more movements than our competitors. The stresses induced on the individual layers of Flex-Weld bellows are a fraction of the stresses induced in single wall bellows of equal thickness. This results in Flex-Weld bellows having a much highercycle life and lower spring rates than our competition.The Single Source for All your BellowsRequirements!AVAILABLE MATERIALSTOLL FREE: 1-800-323-6893Military Cryogenic UHV NuclearNational Labs ValveT-321 Stainless Steel T-316 (L) Stainless Steel T-304 (L) Stainless Steel T-347 Stainless Steel BrassBeryllium Copper Phosphor BronzeCarpenter Alloy 20Inconel 625 Inconel 625 LCF Monel 400Hastelloy C-276, C-22, C-2000Haynes 230 Hastelloy B, B2 TitaniumOther alloys available upon requestTYPICAL APPLICATIONSExpansion Joint AccumulatorElectrode or Shaft SealingMechanical SealingRotary Seal Housing Air Pressure Control Pressure DetectorRemote Transmission& Flow ControlMARKETSValve Repair Steel PaperEngine/ Exhaust Petrochemical PharmaceuticalPower Generation Commercial Instrumentation Vacuum Process ElectronicAutomotive Aerospace Medical Industrial HVACSemiconductorLOWER THRUST FORCES - The multi-ply design results in lower spring rates. Also, the effective cross sectional area of multi-ply bellows is less, compared to single-ply bellows, to accommodate a given movement. These two reduc-tions result in lower forces and moments on the anchors, equipment and guides. A side benefit is that less anchors and guides will be required in the overall bellows piping system.FLEX -WELD FEATURES:ADVANTAGES:Increased flexibility Higher pressures attainable Lower thrust forcesMinimal installation length required Fail safe designElevated corrosion resistanceMULTI-PLY SAFETY FACTORS - In a critical application, a multi-ply bellows assembly can in most cases preclude a catastrophic failure. If a failure occurs in one ply due to corrosion or fatigue, the intact plies will work as a protective barrier to contain the pressure and the medium until a replace-ment can be made. Flex-Weld Multi-ply bellows are designed to provide utmost safety in the event of system failure. The burst pressures are a multiplier of the operating pressure making the Flex-Weld multi-ply bel-lows the most reliable component in the system.CYCLE LIFE OPTIMIZATION - The technical advantage of using multiple plies of .002” - .006” wall thickness material is that less residual stresses are intro-duced at the time of bellows forming. Overall, Flex-Weld multi-ply bellows have lower built-in and induced stresses which ultimately results in longer cycle life. Also, the thinner gauge multiple plies have less localized induced stresses dur-ing operation compared to a single thicker ply. The configuration of the convo-lutions (pitch, depth, contour, number of plies, ply thickness) of FLEX-WELD multi-ply bellows are optimized to offer the highest fatigue life.COMPACT DESIGN - Multi-ply bellows have more flexibility than conventional sin-gle-ply bellows and thus require less live length to accommodate a given move-ment. The live length of the bellows can be minimized to absorb a given combi-nation of axial, lateral and angular movements. This results in an economical compact assembly which can be installed in a minimal amount of space. An ad-ditional benefit is a small effective area resulting in lower thrust pressures onthe anchors and mechanical equipment in the system.Proprietary forming techniques produce metallic bellows of consistent quality and close tolerances.In-process testing & inspection result in the most reliable bellows.Mechanically forming one convolution at a time minimizes material thinning. High frequency pulse TIG welds minimize the heat –affected (HAZ) zone and re-sults in superior bellows strength, ductility and dependability. Diameters ranging from 1/8” I.D. to 280" I.D.Pressures ranging from vacuum to 10,000 PSI depending on application.

冷却设备控制阀安全公告RSBCV安全程序介绍说明书

Refrigeration Control Valves Safety Bulletin RSBCV Safety ProceduresIntroductionThis bulletin is a summary of safety procedures for the proper selection, installation, use and maintenance of Refrigerating Specialties Division industrial refrigerant control valves. Additional free copies are available and should be distributed to all concerned personnel. This bulletin is intended to help you protect your personnel, product and plant. Because of space imitations, this bulletin must be supplemented by accepted and known industry safety practices and local code requirements. Refrigerating Specialties Division control valvesare designed and built to the highest standardsof the refrigeration industry. However, for proper performance the valves must be correctly chosen, properly installed and periodically serviced. Because safe operation is of primary concern, this bulletin emphasizes suggestions for the safe installation and maintenance of Refrigerating Specialties Valves. Read this information carefully before installing a valve or working on one already installed; also, use it to review all previous installations.All personnel working on valves must be qualified to work on refrigeration systems. Any person intendingto service a valve should completely read this bulletin and the product bulletin describing the particular valve and its operation before any work begins. If there are any questions, contact Refrigerating Specialties before proceeding with the work.Receiving and UnpackingAll control valves are packed for maximum protection. Unpack carefully. Flange bolts are packed in cotton bags and coils are packed loose. Check the carton to make sure all flanges and other items are unpacked and in agreement with the packing slip. Save the enclosed instructions for the installer and eventual user. Do not remove the protective covering from the inlet and outlet of the control valve until the valve is ready to be installed.Caution: Do not, at any time, make any alteration or modifications to any Refrigerating Specialties Division valves or regulators without the express and written approval of this company. Threaded parts should not be subjected to excessive torque by use of an oversized wrench, wrench extension or by impacting the wrench handle. Where specified in the individual bulletin, observe the torque requirements for bolts, screws and other threaded parts. Contact the factory for torque values not furnished in current literature.For extensive repairs on valves or regulators, especially those more than three years old, the valves or regulators should be returned to the factory for thorough inspection and rebuilding. Spare parts should be checked for corrosion before installation. In addition, part numbers should be checked againstthe latest assembly bulletin to be sure current parts arebeing used.If a valve or regulator has failed under circumstanceswhich caused, or could have caused, injury topersonnel or damage to property, a replacementvalve should not be installed until the reason for theprevious failure is determined and corrected. Adequateprotection should be taken to prevent both liquid shockand suction shock both upstream and downstream ofthe valve or regulator.Liquid ExpansionIn liquid lines, or lines that might contain substantialamounts of liquid refrigerant, certain precautions mustbe taken to avoid damage due to liquid expansionwhen a section of line is isolated by positive shutoff valves. This condition may occur whenever theambient temperature could be higher than the liquidtemperature. This could even occur in a refrigerant oroil line other than a “liquid” line.Temperature increase in a section with trappedliquid can cause extremely high pressures due to theexpanding liquid and possibly rupture a gasket, pipe,or valve. When low temperature liquid lines are used,as in a liquid overfeed (recirculation) system, andthe lines or control valves may be exposed to warmambient conditions, particular care must be taken;liquid expansion can occur very rapidly.Check ValvesCheck valves must never be installed at the inlet ofeither a solenoid valve, a regulator or a regulator withan electric solenoid pilot shut-off feature. Also, thecheck valve should not be installed at the inlet of anoutlet pressure regulator in a system where liquid maybe trapped between the two valves. If a check valve isneeded, install it on the outlet side of such valves. Mostsolenoid valves and regulators will permit reverse flowif the outlet pressure is greater than inlet pressure. If atany time, such reverse pressure conditions are possibleand reverse flow is unacceptable a check valve shouldbe installed at the control valve outlet.All hand valves that could trap liquid when closed mustbe marked with a warning against accidental closing.The liquid refrigerant must be removed before the handvalves are closed on both sides of a control valve or anyother component. Also, liquid must be removed beforea hand valve is closed at the inlet of a solenoid valveor a regulator with positive electric shut-off, or someoutlet pressure regulators, or at the outlet of a checkvalve, unless these valves are manually open.Caution: To protect personnel, product and plant,remove all liquid from the section to be isolated beforehand valves are closed. Make sure the control valvesare open when removing the liquid. See Service andMaintenance Instructions before attempting to takeany valve apart.Relief DevicesRelief devices or relief methods should be used in allparts of a refrigeration system where liquid can betrapped and liquid expansion could take place. Underno circumstances should R/S Pressure Regulators beused as a relief to the atmosphere, R/S Type H SafetyRelief valves should be used instead.Selection and ApplicationA control valve must be selected only by a personhaving adequate knowledge of the system and ofthe valve to be chosen. Any Refrigerating SpecialtiesDivision control valve must be used only as specificallystated in Refrigerating Specialties Division Catalogsor Bulletins for normal refrigeration applicationsunless otherwise approved in writing by RefrigeratingSpecialties Division.The valves are designed to operate with ammoniaand/or halocarbon refrigerants. Valves using flangeswith copper connections must not be used withammonia refrigerant. Unless authorized by the factory,Refrigerating Specialties valves should not be used forrefrigerants or fluids not mentioned on the nameplateor in the pertinent bulletin.InstallationInstallation must be done according to all applicableSafety Codes and Standards, and by personnelqualified to install refrigeration systems. RefrigeratingSpecialties Division control valves must be installedaccording to the manufacturer’s instructions, thisbulletin, and the generally known safety practices.MountingASTM A307 Grade A square headed bolts should beused to mount flanged body valves. They assure themaximum bolt surface and flange engagement. For alllug mounted valves, flange bolts should be inserted ina direction pointing toward the valve body. The boltshould pass first through the mounting flange beforeengaging the valve flange. Allow proper space forinstalling the valve. Do not use the valve to “stretch”or “align” the pipe. Using flange bolts to close a largegap can distort the valve or at least stress it unduly, andpossibly cause it to malfunction, or the bolts may bedamaged or stripped.Verify that piping into which a valve or flange is tobe installed is properly supported and aligned. Becertain that the mating surfaces of the gasketedjoints are parallel, aligned and perpendicular to thepipe axis, in good condition and free of debris andcorrosion. Use only undamaged gaskets suitable forservice in an ammonia refrigerating system. Verifythat all the nuts, bolts, cap screws and washers meetParker’s requirements for the application and tightenprogressively in a diametrically staggered pattern.Leak test upon completing the installation. For moreinformation please reference the IIAR 2-2008 Section10.When mounting weld-end valves: welding proceduresfor all steel pipe and fitting need to conform to allrequirements of the ASME IX and other PressurePipe welding standards. In all cases where valves areinstalled without disassembly, they should be manuallyopened.LocationValves must not be installed in locations wherethey can be damaged by material handling or otherequipment. Control valves should be installed such© 2012 Parker Hannifin CorporationParker Hannifin CorporationRefrigerating Specialties Division 2445 South 25th. Avenue Broadview, IL 60155-3891phone (708) 681-6300 fax (708) 681-6306/refspecPage 2 / Safety Bulletin RSBCV050006 D 08/15/12that the inlet pipe is straight for a minimum of 6 pipe diameters. Trapped ice build-up must be avoided at or between valves and other equipment. Provide reasonable access to all control valves for maintenance purposes.InsulationWhen it is necessary to insulate the control valves, the insulation must be applied to allow access for proper operation and maintenance of the valves. The manual opening and adjusting stems should be easily accessible at all times. In the case of solenoid valves the insulation must not extend to the coil housing or coil burnout may occur. Insulation should be constructed so that sections can be easily removed and replaced to allow the valve to be disassembled. Insulation applied to strainers should provide ready access for cleaning the strainer basket.Since most maintenance problems caused by dirtoccur at the start-up of a system, it is advisable to delay insulating the control valves and strainers until the system has operated for several days. During that time the strainers should be checked for dirt and cleaned as necessary. Cotton bags are available for 25mm-100mm (1” - 4”) Type RSF Strainers to improve their ability to remove small particles of dirt during start-up.Pump Out MeansIndividual valves or control stations should be provided with means for pumping out or safely purging the refrigerant.Pressure TestingEvery segment of a refrigeration system, including control valves, should be field pressure tested before system is insulated and put in use. Make sure that correct high and low side test pressures are used. Use proper refrigerant or gas for pressure testing; that is do not use halocarbons or CO 2 to test an ammonia system, nor use ammonia to test halocarbon system. Never use the compressor in a system to build up pressure for testing.In pressure testing Range V , VA, A, B or D pressure regulators, test pressure in excess of 21. kg/cm 2 (300 psig) may cause setting shift and diaphragm may deform enough to require replacement after the test. If the above conditions exist, contact the factory for proper solution.ElectricalOnly properly qualified electricians should handle the electrical portions of control valves and their circuitry. All power supplies and wiring must be adequate to provide the proper voltage and current to the solenoid coils. The power supply must be capable of providing the proper in-rush current. Never energize the solenoid with the coil housing or plunger assembly removed.Before working on any valve be sure the circuits are completely de-energized; just throwing a switch may not be sufficient. Failure to do this may result in personal injury or damage to solenoid coils or other components. Take care to see that the circuits cannot be energized accidentally. Never energize the solenoid with the coil housing or plunger assembly removed.Service and MaintenanceAll systems require maintenance and service. The personnel doing the work must be qualified andcompletely familiar with the system they are to work on or all other precautions will be meaningless.Pump OutFor the protection of personnel, product, and plant, all refrigerant possible must be removed from a valve or any other component of the system, before any refrigerant retaining part is loosened. Before opening a valve, make sure all refrigerant liquid has been removed. In particular, beware of strainers and other sections of piping which may trap liquid refrigerant which will require a considerable length of time to remove. Pump out as much refrigerant as possible before discharging remaining refrigerant in a properly protected manner. During pump out make sure control valves are opened manually to avoidtrapping refrigerant. All type RSF and RSW Strainers are provided with 3/8” FPT connection to assist in pump out.At times it may be necessary to discharge some small amount of refrigerant from the isolated section. When this becomes necessary, certain precautions must be observed. Make sure control of discharge rate can be easily maintained and that a quick shut-off is available. Refrigerant should be discharged into and disposed of in a proper container accepted by applicable safety codes and standards. Discharge of refrigerant to atmosphere should be avoided. Never discharge any refrigerant into an area without sufficient ventilation, or into an area where open flame or electrical spark is present. Any oil in the refrigerant may cause a mist that could cause a fire or explosion. Halocarbon refrigerant should not be discharged into areas where open flame is present, since toxic gases may form. Ammonia should not be discharged into occupied areas, or areas containing product affected by ammonia. In the case of ammonia, discharge any vapor left into a container of cold water, making sure that the discharge hose remains submerged at all times. (Be sure that no pressure reversals can occur that may pull water into the system.) Water may have to be refreshed to absorb all the ammonia; about one gallon of fresh water is needed for one pound of ammonia. To prevent pulling excessive air and moisture into a system, avoid opening the system when it is under vacuum.Caution: Do not attempt to work on any part of a refrigeration system without having help nearby and observing. Use safety glasses or a safety face shield for added safety to protect the eyes. Protective equipment should be readily available and all personnel involved should be thoroughly trained in its use. Personnel should be especially protected against falling because they may be startled by escaping refrigerant. Always make sure that there is a way out and that everyone can leave the area fast. When seal caps cover manual opening or adjusting stems, the caps must beremoved with caution because liquid refrigerant could accumulate under such a cap. Avoid contact with any liquid refrigerant.DisassemblyBe sure that any person working on a valve is familiar with its construction and operation by referring to theproper bulletin. Make sure the pressure in the system to be opened is reduced to, and remains, at atmospheric pressure before valve pressure containment seals are released. A pressure gauge should be connected to the part of the system to be evacuated. Before removing the bonnet of pressure regulators, back out adjusting stem to prevent damage to the diaphragm.Re-assemblyBe sure all parts are clean and free of moisture before reassembly. Damaged parts and gaskets should be replaced. It is advisable to purge the section of air before opening it to the rest of the system. Whenopening hand valves, ensure that initial refrigerant flow will be in the normal direction of valve flow; this will avoid backflow and possible damage to the strainer if one is used.Dirt, Contamination, and CorrosionProtect the valves from foreign material during storage and installation. The protective plugs on the valve openings should remain in place until the valves are ready to be installed. Once a section of a system is installed, and before it is put into operation, it is advisable to charge it with appropriate refrigerant or suitable inert gas to avoid corrosion. Avoid exposure of R/S valves to halogenated solvents or similar reactive fluids. External corrosion over a long period of time must be controlled by painting and replacement of corroded parts.Strainer MaintenanceStrainer inspection is of utmost importance, especially the first few hours, days or weeks after the start-up. Foreign material should be removed and the screens should be washed with proper solvent. Strainer inspection and cleaning should be continued until dirt accumulation ceases. Later, any time a valve pressure containment seal is released for service or maintenance, its companion strainer should also be inspected and cleaned. Filter bags are available for 25mm-100mm (I” - 4”) Type RSF Strainers to improve their ability to remove small particles of dirt during start-up. If a strainer filter bag is used in the strainer basket, the cloth bag must be checked every few days depending upon the amount of system dirt collected. When the cloth bag no longer collects dirt, it must be discarded.General SpecificationsRefrigerating Specialties refrigerant containing valves and strainers are designed for a maximum rated pressure of 27.6 bar (400 psig) except where shown otherwise on the nameplate. They are suitable for use under most temperature conditions encountered in refrigeration systems. Maximum and minimum fluid temperatures for each valve are published in Industrial Refrigerating Control Valve Catalog C12. If either fluid or ambient temperature is below a valves rated minimum, consult the factory.

The relevent procedures recommended by Dresser Valve and Controls Division (DVCD), and described in this manual, are effective methods of performing the required tasks. Some of these procedures require the use of tools specifically designed for an intended purpose. These special tools should be used when, and as, recommended.It is important to note that this manual contains various “safety messages”which should be carefully read in order to minimize the risk of personal injury, or the possibility that improper procedures will be followed which may damage the involved DVCD product, or render it unsafe. It is also important to understand that these “safety messages” are not exhaustive.DVCD can not possibly know, evaluate, and advise any customer of all of the conceivable ways in which tasks might be performed, or of the possible hazardous consequences of each way. Consequently, DVCD has not undertaken any such broad evaluation and, thus, anyone who uses a procedure and/or tool, which is not recommended by DVCD, or deviates from DVCD recommendations, must be thoroughly satisfied that neither personal safety, nor valve safety, will be jeopardized by the method and/or tools selected. If not so satisfied, contact DVCD (at 318/640-2250) if there are any questions relative to tools/methods. Some of the products manufactured by DVCD may be used in radioactive environments.Consequently, prior to starting any operation in a radioactive environment,the proper “health physics” procedures should be consulted and followed,if applicable.The installation, operation and maintenance of valves and/or valve products may involve proximity to fluids at extremely high pressure and/or temperature. Consequently, every precaution should be taken to prevent injury to personnel during the performance of any procedure. These precautions should consist of, but are not limited to, ear drum protection,eye protection, and the use of protective clothing. (i.e., gloves, etc.) when personnel are in or around a valve work area. Due to the various circumstances and conditions in which these operations may be performed on DVCD products, and the possible hazardous consequences of each way, DVCD can not possibly evaluate all conditions that might injure personnel or equipment. Nevertheless, DVCD does offer the safety precautions listed on page 3 for customer information only.It is the responsibility of the purchaser or user of DVCD valves/equipment to adequately train all personnel who will be working with the involved valves/equipment. Further, prior to working with the involved valves/equipment, personnel who are to perform such work should become thoroughly familiar with the contents of this manual. Accordingly, should additional copies of this manual be required, they can be purchased, at a minimal cost, by contacting DVCD (in writing) at P.O. Box 1430, Alexandria,LA 71309-1430, or (telephonically) at 318/640-2250.Wear necessaryII.Safety PrecautionsFollow all plant safety regulations, but be sure to observe the following:•Do not stand in front of the discharge side of a safety relief valve when testing or operating.•Hearing protection should be used when testing or operating a valve.•Exercise care when examining a safety relief valve for visible leakage.•Never install a safety relief valve in a horizontal position. Safety relief valve internals are designed to move vertically. When installed horizontally, misalignment and galling, or hang-up, may prevent the valve from opening or closing properly.•Safety relief valves should be mounted to provide adequate access, 360°around the valve plus overhead, to permit removal for testing and maintenance.•When removing a safety relief valve for disassembly, stand clear and/or wear protective clothing to prevent exposure to splatter of any corrosive process medium which may have been trapped inside the valve. Ensure the valve is isolated from system pressure before the valve is removed.•When a valve is equipped with a lifting lever, the lever should be positioned to avoid unintentional contact with other equipment, or with personnel, which might cause the valve to lift accidentally.•All valves require periodic inspection and tests by qualified persons to insure that the valves are in proper working condition, and will function as designed by DVD.•The owner/operator of the valves must be aware of usage conditions, and must bear the responsibility for determining the appropriate frequency of examination of the valves.Warranty Information1.*Warranty StatementDresser warrants that its products and work will meet all applicable specifications and other specific product and work requirements(including those of performance), if any, and will be free from defects in material and workmanship.Defective and nonconfourming items must be held for Dresser'sinspection and returned to the original F.O.B. point upon request.2.Incorrect Selection or Misapplication of ProductsD.V.D.cannot be responsible for customer's incorrect selection ormisapplication of our products.3.Unauthorized Repair WorkD.V.D. has authorized no non-Dresser affiliated repair companies,contractors nor individuals to perform warranty repair services on new products of field repaired products of its manufacture.

Telephone (318)640-2250Page 3CON-16Page 4III.IntroductionThe Consolidated® Series 19000 portable pressure relief valves are designed tomeet ASME Section VIII requirements for fixed blowdown pressure relief valvesand liquid relief valves. They may be used for various media such as air, liquids,process steam and hydrocarbons, and may serve as either a safety valve or arelief valve, depending upon the application.IV.Terminology for Safety Relief Valves•AccumulationAccumulation is the pressure increase over the maximum allowableworking pressure of the vessel during discharge through the pressurerelief valve, expressed as a percentage of that pressure, or actualpressure units.•Back PressureBack pressure is the pressure on the discharge side of a safety relief valve.(Also see “Built-Up Back Pressure” and “Superimposed Back Pressure”,below.)•BlowdownBlowdown is the difference between set pressure and reseating pressureof a pressure relief valve, expressed as a percentage of the set pressure,or actual pressure units.•Built-up Back PressureBuilt-up back pressure is pressure which develops at the valve outlet asa result of flow, after the safety relief valve has been opened.•ChatterChatter is the abnormal, rapid reciprocating motion of the movable partsof a valve in which the disc contacts the seat.•Closing PressureClosing pressure is the point at which the valve recloses.•Cold Differential Set PressureCold differential set pressure is the pressure at which the valve is adjustedto open on the test stand. This pressure includes the corrections for backpressure and/or temperature service conditions.•Differential Between Operating and Set PressuresValves in process service will generally give best results if the operatingpressure does not exceed 90% of the set pressure. However, on pumpand compressor discharge lines, the differential required between theoperating and set pressures may be greater because of pressure pulsationscoming from a reciprocating piston. It is recommended that the valve beset as high above the operating pressure as possible.CON-16Page 5IV.(Continued)•FlutterFlutter is the abnormal, rapid reciprocating motion of the movable parts ofa valve in which the disc does not contact the seat.•LiftLift is the actual travel of the disc away from the closed position when avalve is relieving.•Maximum Allowable Working PressureMaximum allowable working pressure is the maximum gauge pressurepermissible in a vessel at a designated temperature. A vessel may not beoperated above this pressure, or its equivalent, at any metal temperatureother than that used in its design. Consequently, for that metal temperature,it is the highest pressure at which the primary safety relief valve is set toopen.•Operating PressureThe operating pressure is the gauge pressure to which the vessel isnormally subjected in service.•OverpressureOverpressure is a pressure increase over the set pressure of the primaryrelieving device. Overpressure is similar to accumulation when therelieving device is set at the maximum allowable working pressure of thevessel. Normally, overpressure is expressed as a percentage of setpressure.•Rated CapacityRated capacity is the percentage of measured flow at an authorizedpercent overpressure permitted by the applicable code. Rated capacityis generally expressed in pounds per hour (lb/hr) for vapors; standardcubic feet per minute (SCFM) or m3/min for gases; and in gallons perminute (GPM) for liquids.•Relief ValveA relief valve is an automatic pressure-relieving device, actuated by staticpressure upstream from the valve. This type of valve is used primarily forliquid service.•Safety Relief ValveA safety relief valve is an automatic pressure-relieving device which maybe used as either a safety or relief valve, depending upon application.•Safety ValveA safety valve is an automatic pressure-relieving device actuated by thestatic pressure upstream of the valve, and characterized by rapid openingor pop action. This type of valve is used for steam, gas or vapor service.•Seat Tightness PressureSeat tightness pressure is the specified inlet static pressure at which aquantitative seat leakage test is performed in accordance with a standardprocedure.CON-16Page 6IV.(Continued)•Set PressureSet pressure is the gauge pressure at the valve inlet, for which the safetyrelief valve has been adjusted to open under service conditions. In liquidservice, set pressure is determined by the inlet pressure at which the valvestarts to discharge. In gas or vapor service, the set pressure is determinedby the inlet pressure at which the valve pops.•SimmerSimmer is characterized by the audible passage of a gas or vapor acrossthe seating surfaces just prior to "pop". The difference between this "startto open pressure" and the set pressure is simmer, and is generallyexpressed as a percentage of set pressure.•Superimposed Back PressureSuperimposed back pressure is the pressure in the discharge headerbefore the safety relief valve opens. This can be further defined as follows:Constant Superimposed - This type of back pressure remains essentiallyat a fixed value (constant) and exists (superimposed) continuously prior toand during opening of the valve. (e.g., 20 psig/1.38 bar).Variable Superimposed - This type of back pressure varies or changesover a range from a minimum to a maximum, or vice versa. (e.g., 0 to 20psig/1.38 bar). The actual back pressure at any specific time depends onconditions in the piping system to which the outlet of the valve isconnected.•Valve TrimValve trim includes the nozzle and disc.V.Design Features and NomenclatureA.Design Features1.General InformationThe Series 19000 portable safety relief valve has 316 stainlesssteel trim as standard material. Reliable performance and easymaintenance procedures are characteristics of this valve, whenproperly installed in suitable applications for its design.The 19000 Series SRV has three pressure classes, 19000L5-290 psig, 19000M 291-2000 psig, and 19000H 2001 and up.Standard 19000 parts are used for both liquid applications andgas applications. It is designed for short blowdown on allmedias, typically less than 10%.CON-16Page 7 V.A.(Continued)All19000 Series safety relief valves have fixed blowdown. Thismeans that the parts are designed so that there is no blowdownadjustment required when setting or testing the valve.2.Design Optionsa.O-ring seat seal valvesAll 19000 Series Valves are available with an O-ring seatseal, as a design option. This optional design provides abubble tightness in excess of 97% of the valve set pressure,in order to meet application requirements beyond thenormal capabilities of metal to metal seat valves.Consolidated®Series 19000 Valves with the O-ring seatseal option are identified by the suffix DA (e.g., 1-19096L-DA).b.Lifting Levers, Caps and GagsAll 19000 Series Valves are designed so that field conversionfrom the standard screwed cap to a plain lifting lever cap, orto a packed lifting lever cap (or vice versa) does not requirevalve disassembly or resetting. The lifting lever option isdesigned to open the valve at 75% of the valve set pressure,in compliance with ASME Code Section VIII. Further, allavailable 19000 Series Valve caps may be equipped with agag, upon customer request.c.Inlet/Outlet ConnectionsAll 19000 Series Valves can be provided by DVD withflanged, or socket weld inlet and outlet connections, uponcustomer request.B.NomenclatureApplicable valve nomenclature for Types 19000 Male and Femaleinlet configurations are illustrated in figures 1 through 3.

This would be most likely to occur by bumping or dropping during loading or unloading from a truck. While hoisting to the installation,care should be taken to prevent bumping the valve against steel structures and other objects.NOTE:Never lift the full weight of the valve by the lifting lever (if the valve is so equipped).B.StorageSafety relief valves should be stored in a dry environment to protect them from the weather. They should not be removed from the crates until immediately prior to installation.Protectors and sealing plugs (both inlet and outlet) should not be removed until the valve is ready to be installed.C.Pre-installationWhen safety relief valves are uncrated, and the protectors or sealing plugs have been removed (immediately prior to installation), meticulous care should be exercised to prevent dirt and other foreign materials fromentering the inlet and outlet ports.Page 13 VII.Recommended Installation PracticesA.Mounting PositionSafety relief valves should be mounted in only a vertical upright position (per API RP520). Installing a safety relief valve in other thana vertical position (±1 degree) will adversely affect its operation invarying degrees, as a result of induced misalignment of moving parts.A stop valve may be placed between the pressure vessel and itsrelief valve only as permitted by code regulations. If a stop valve is located between the pressure vessel and safety relief valve, the stop valve port area should equal or exceed the nominal internal area associated with the pipe size of the safety relief valve inlet. The pressure drop from the vessel to the safety relief valve shall not exceed 3% of the valve's set pressure, when flowing at full capacity.The inlet and outlet ports, and sealing faces, of the valve and all connecting piping must be free from dirt, sediment and scale.Safety relief valves should be located for easy access and/or removal so that servicing can be properly performed. Sufficient working space should be provided around, and above, the valve.B.Inlet PipingThe inlet piping (see Figure 8), to the valve should be short and direct from the vessel, or equipment, being protected. The connection to the vessel should be provided with a radius to permit smooth flow to the valve. Sharp corners should be avoided. If this is not practical, then the inlet should be bored at least one additional pipe diameter.In any event, the pressure drop from the vessel to the valve should not exceed 3% of valve set pressure when the valve is flowing full capacity. In no event should the inlet piping be smaller in diameter than the inlet connection of the valve. Excessive pressure loss at the inlet of a pressure relief valve in gas, vapor, or flashing-liquid service will cause extremely rapid opening and closing of the valve, which is known as “chattering”. Chattering will result in lowered capacity and damage to the seating surfaces. The most desirable installation is that in which the nominal size of the inlet piping is the same as, or greater than, the nominal size of the valve inlet, and in which the length does not exceed the face-to-face dimensions of a standard tee of the required pressure class.Safety relief valve inlets should not be located at the end of a long horizontal pipe through which there is normally no flow. Foreign matter may accumulate, or liquid may be trapped, and may interfere with the operation of the valve, or be the cause of more frequentvalve maintenance.CON-16CON-16VII.B.(Continued)Safety relief valve inlets should not be located where excessive turbulence is present such as near elbows, tees, bends, orifice plates, or throttling valves.Section VIII of the ASME Boiler and Pressure Vessel Code requires that the design of the inlet connection consider stress conditions incuded by reaction forces during valve operation, by external loading, by vibration and by loads due to thermal expansion of discharge piping.Page 141.The determination of reaction forces during valve discharge isthe responsibility of the vessel and/or piping designer. DVD publishes certain technical information about reaction forces under various fluid flow conditions, but assumes no liability for the calculations and design of the inlet piping.2.External loading by poorly designed discharge piping andsupport systems can be the cause of excessive stresses and distortions in the valve as well as the inlet piping. The stresses set up in the valve may cause malfunctioning or leakage of the valve. Forced alignment of the discharge piping will also induce such stresses. Discharge piping should be independently supported and carefully aligned.FIGURE 8THE PRESSURE DROP (P.D.)BETWEEN THE SOURCE OFPRESSURE IN THE PROTECTEDEQUIPMENT AND THE PRESSURERELIEF VAVE INLET IS NOT TOEXCEED 3% OF THE VALVESET PRESSURE.CON-16 3.Vibrations in the inlet piping systems may cause valve seatleakage and/or fatigue failure of the piping. These vibrations may cause the disc seat to slide back and forth across the nozzle seat and result in damage to the seating surfaces.Vibration may also cause separation of the seating surfaces and premature wear to certain valve parts. High-frequency vibrations are more detrimental to pressure relief valve tightness than low-frequency movements. This effect can be minimized by providing a larger difference between the operating pressure of the system and the set pressure of the valve, particularly under high-frequency conditions.4.Temperature changes in the discharge piping may be causedby fluid flowing from the discharge of the valve, prolonged exposure to the sun, or heat radiated from nearby equipment.Any change in temperature of the discharge piping will cause a change in the length of the piping. The resulting change in length may cause stresses which will be transmitted to the pressure relief valve and its inlet piping. Stresses caused by thermal changes in the discharge piping can be avoided by proper support, anchoring, or provision for flexibility of the discharge piping. Fixed supports should not be used.C.Outlet PipingAlignment of the internal parts of a safety relief valve is important to ensure proper operation (see Figure 9). Although the valve body will withstand a considerable mechanical load, unsupported discharge piping consisting of more than a companion flange, long radius elbow and a short vertical pipe is not recommended. Care should be taken to ensure thermal expansion of piping and support system does not produce strains in a valve.Spring supports are recommended where this may be the case. The discharge piping should be designed to allow for vessel expansion as well as expansion of the discharge pipe itself. This is particularly important on long distance lines.Page 15VII.B.(Continued)FIGURE 9CON-16Consideration should be given to discharge pipe movement resulting from wind loads, since a continual oscillation of the discharge piping introduces stress distortion in the valve body, and the resultant movement of the internal parts may cause leakage.As a final point, the discharge piping size is never less than the size of the valve outlet, it shall not be heavier than schedule 40 pipe size,and the discharge piping must be designed to limit the total backpressure to a maximum of 10% of the valve set pressure, or 400psi, whichever is smaller.Page 16VII.C.(Continued)VIII.Disassembly InstructionsA.General InformationConsolidated ® Safety Relief Valves can be easily disassembled for inspection,reconditioning seats,or replacing internal parts.Appropriate set pressure can be established after reassembly.(Refer to Figure 1 thru Figure 7 for Parts Nomenclature.)NOTES:•Before starting to disassemble the valve, be sure that thereis no media pressure in the vessel.•Many pressure vessels that are protected by Consolidated ®Safety Relief Valves contain dangerous materials.Decontaminate and clean the valve inlet and outlet and all external surfaces in accordance with the cleaning and decontaminating recommendations in the appropriate Material Safety Data Sheet.•Parts from one valve should not be interchanged with partsfrom another valve.B.

Tag shutoff or bypass valves toguard against a “turn-on” while work is in progress.Bleed air from actuator and check that valve is in itsunenergized position.It is now safe to disconnect and remove any valve mounted equipmentthat is being replaced.For the procedure to mount rotary and reciprocating valves, refer to theMounting Instructions contained in the valve’s Mounting Box kit.Installing the SVI II AP Remote Position Sensor An option that is available for the SVI II AP is the Remote Position Sensor. The Remote Position Sensor, is a remotely mounted position-sensing device, that is connected electrically to an SVI II AP valve positioner. It is used as position feedback in applications where direct mounting of an SVI II AP to a valve actuator is not practical due, typically but not limited to, extreme vibration, heat or radiation.The Remote Position Sensor is a potentiometer located in an enclosure which can be mounted on a valve or damper to indicate stem position when connected to a suitable receiver. There is a three wire connection provided on a screw terminal block to interconnect to the receiving device.The SVI II AP Remote Position Sensor is suitable for installation outdoors in an industrial environment. Mounting kits are provided topermit mounting on a variety of valves.Do not remove the instrument cover or connect to an electrical circuit ina Hazardous Area unless the power is disconnected.Comply with current national and local regulationsfor electrical installation work.Installation and Set Up Installing the SVI II AP Remote Position SensorComply with national and local explosiveatmosphere regulations.Before carrying out any work on the device, poweroff the instrument or make sure that the localeconditions for potentially explosive atmospherepermit the safe opening of the cover.Installation ProcedureFor the Remote Position Sensor installation procedure refer to themounting instructions provided with the Remote Position Sensor.1.Remove the cover from the Remote Position Sensorassembly by turning the cover in a counter-clockwise (fac-ing the cover) direction.2.Connect the Remote Position Sensor to the mountingbracket by inserting four M6 x 20 mm Socket Head CapScrews through the appropriate screws holes (accordingto the valve) on the Remote Position Sensor bracket andusing a 3⁄16 inch Hex Key with tee handle.3.Route the instrument cable from the SVI II AP to theRemote Position Sensor (see Figure 3 on page 6 forinstallation instructions).4.Thread the cable through the conduit at the bottom of theRemote Position Sensor.ing a blade screwdriver, loosen the screws on theterminal block and connect the black, brown and red wiresto the appropriate labelled connectors.6.Tighten the screws.7.Attach the feedback lever to the Remote Position Sensorshaft. From the cover side, the lever should be pointing tothe left for reciprocating valves and to the right for rotaryvalves.8.Place the Remote Position Sensor on the mountingbracket.9.Attach the Remote Position Sensor and secure theturnbuckle to the lever ensuring that the shaft at the rear ofthe Remote Position Sensor is inserted into the valveactuator.

This section describes the process for connecting the tubing and air supply to a single and double actingpositioner.Isolate the valve from the process and disconnect air tubing from the positioner. Disconnect air fully to avoid injury or process damage.1.Install the pneumatic tubing using a regulated, clean,instrument air supply to the air supply port (S←)2.For a single acting actuator - pipe the outbound air fromthe output pressure port (←I) to the valve actuator.3.For a double acting actuator - pipe the air going out ofeach side of valve actuator. Use both output pressure portone (←I) for one side of the actuator and output pressureport two (←II) for the other side of the actuator.4.Connect air supply and actuator outports (1⁄4 inch NPT)Supply pressure for single acting SVI II AP:20 -100 psi (1.4 - 6.9 bar) (138 - 690 kPa)Supply pressure for double acting SVI II AP:20 - 150 psi (1.4 - 10.4 bar) (138 - 1035 kPa)Minimum tubing diameter 1⁄4 inch (6mmx4mm) Note:The SVI II AP Digital Positioner is designed to operate with clean, dry, oil-free, instrument grade air to ANSI-ISA-57.3 1975(R1981) or ISA-S7.3-1975 (R1981) or with a sweet natural gassupply (SVI II AP models SVI II AP-2 through SVI II AP-3).Table 3Dew Point At least 18° F (10° C) below minimum anticipated ambienttemperatureParticulate Matter Filtered to 5 micronsOil Content Less than 1 ppm w/wContaminants Free of all corrosive contaminantsAir Supply RequirementsMasoneilan Dresser SVI II AP Quick Start Guide Single Acting PositionerThe supply and output connections for the SVI II AP, located on bottomof the pneumatic block, are tapped 1⁄4 inch NPT. Output is toward thefront, supply is toward the back. Two pressure gauges, output on top,supply on bottom, are located on the front of the pneumatic block.Maximum allowable air supply pressure to the SVI II AP variesaccording to actuator, valve size, and valve type. See Pressure Droptables in valve specification sheets to determine the correct positionersupply pressure. Minimum supply pressure should be 5 to 10 psi abovemaximum spring pressure but may not exceed the rated actuatorpressure.OutputSupplyFigure 4Air Ports on Single Acting PositionerInstallation and Set Up Connecting the Tubing and Air Supply Double Acting PositionerConnect Output 1, labeled “(←I)” to the inlet port of the actuator andconnect Output 2 labeled “(←II)” to the opposing actuator port (seeFigure 5 below for double acting ports.Output I ConnectorSupply Connector Connector Output IIFigure 5Air Ports on Double Acting PositionerConnecting the Air SupplyAfter the tubing is installed, use the following procedure to connect theair supply.1.Connect a supply of clean, dry compressed air to the filterregulator.2.Turn on the air supply.3.Adjust the filter regulator.4.Supply pressure must be 5 - 10 psi greater than the springrange of the actuator but may not exceed the ratedactuator pressure. Refer to the valve or actuatorinstruction manual.Masoneilan Dresser SVI II AP Quick Start GuideWiring the SVI II AP In order for the SVI II AP to communicate the positioner data the SVI II AP must be physically connected to a HART communication. The procedure below outlines wiring the SVI II AP.Comply with current national and local regulationsfor electrical installation work.Comply with national and local explosiveatmosphere regulations.Before carrying out any work on the device, poweroff the instrument or make sure that the localeconditions for potentially explosive atmospherepermit the safe opening of the cover.Connecting to the Control LoopThe SVI II APpositioner MUST BE grounded according to localregulations. It is important to maintain correct polarity at all times,otherwise the positioner may not operate properly. The SVI II APshould be physically connected to the HART loop using a cablespecified by the HART Communication Foundation. A shielded cableis recommended.To connect the Control Loop to the SVI II AP:1.Connect one end of the cable to the control loop's4 - 20mA output2.Remove the threaded wiring covers on the positioner.3.Connect the other end of the cable to the SVI II AP. Thereare two threaded openings on the positioner. Use theopening with the red plastic insert.4.Maintain polarity + and - respectively.Wiring GuidelinesThis list contains eight guidelines for a successful implementation of DCcurrent signal, DC power, and HART communication to the SVI II AP:pliance voltage at the SVI II AP must be 9 volts at themaximum current of 20 mA.2.Signal to the SVI II AP must be a regulated current in therange 3.2 to 22 mA.3.Controller output circuit must be unaffected by the HARTtones which are in the frequency range between 1200 and2200 Hz.4.Frequency range of the HART tones must have a circuitimpedance of more than 220 Ohms, typically 250 Ohms.5.HART tones may be imposed by the positioner and acommunication device located anywhere on the signalingcircuit.Installation and Set Up Wiring the SVI II AP6.Capacitance of the signaling circuit must not exceed 0.26microfarads or 0.10 microfarads with high seriesresistance.7.Cabling must be shielded to prevent electrical noise thatwould interfere with the HART tones, with the shieldgrounded.8.Signal must be properly grounded in only one place.Note:For details and calculation methods for wiring resistance, andcapacitance and for calculation of cable characteristics pleaserefer to the HART FSK Physical Layer Specification.SVI II AP SetupsTypical system setups are shown in Figure 6 on page 13, GeneralPurpose and Explosion Proof (EEx d) Installation Schematic and Figure7 on page 13, Intrinsically Safe Installation Schematic. The SVI II APpositioner can be located in a general-purpose or hazardous areaprotected by Explosion Proof (EEx d) methods. Wiring diagrams aregeneralized, actual wiring must adhere to Electrical Installation sectionof manual and local electrical codes. The use of a HandheldCommunicator or a HART modem is not permitted in the HazardousArea protected by Explosion Proof (EEx d) methods. In Figure 7 onpage 13 the SVI II AP positioner is located in a hazardous area that isprotected by Intrinsically Safe wiring practices.The SVI II AP requires an electrical input from a 4-20 mA currentsource. The SVI II AP input signal can carry a HART communicationprotocol signal from ValVue 2.4 or greater software and a HARTmodem, or from a HART Hand Held Communicator. Since the processcontrol system, the source of the input signal, is located in a non-hazardous location, setup requires an intrinsic safety barrier be placedbetween the process control system and the SVI II AP. If the SVI II APis located in a hazardous area with Intrinsically Safe protection a barrieris not required for a flameproof installation. Alternatively the systemcan be installed as Explosion Proof ⁄ flameproof. SVI II AP cancommunicate with a remote PC running ValVue software via a modemconnected to the PC's serial or USB port. The PC, which is notintrinsically safe, must be connected to the circuit on the safe area sideof the intrinsic safety barrier if the valve is located in a hazardous area.The SVI II AP can be operated, calibrated, configured, and interrogatedeither by using local pushbutton and display, or by using a PC runningValVue 2.4 software, HART Handheld Communicator, or any registeredHART Host that supports DDs. The HART Handheld Communicator isapproved for Intrinsically Safe use in accordance with FM and ATEXstandards. Read and observe all HHC labelling. The SVI II AP ispolarity sensitive so the positive lead must be connected to the positive(+) terminal and the negative lead to the negative (-) terminal. Reversalof input will not cause damage but the unit will not function.。
