汇川变频器常规问题解答(060801)

1、MD300系列功率范围是多少？MD320系列功率范围是多少？MD300A系列功率范围是多少？MD300系列功率范围是：单相0.4~2.2Kw，三相0.75-30Kw。

MD320系列功率范围是：单相0.4~2.2Kw ，三相0.75~355KW。

（280G、355P）MD300A系列功率范围是：0.4、0.75Kw2、单相220V变频器的输出电压范围是多少？F1组电机额定频率为50Hz，变频器输出25Hz时，变频器的输出电压（加在电机上的输入电压）是多少？单相220V变频器的输出电压范围是：0~220V。

F1组电机额定频率为50Hz，变频器输出25Hz时，变频器的输出电压（加在电机上的输入电压）是：110V。

3、MD300S1.5和MD300T1.5的额定输出电流分别是多少？为什么差1.732倍？MD300S1.5 额定输出电流是：7.0AMD300T1.5的额定输出电流是：3.8A因MD300T1.5额定输出电压比MD300S1.5额定输出电压大1.732倍，故MD300T1.5额定输出电流比MD300S1.5额定输出电流小1.732倍。

4、客户紧急需要三相220V 15Kw的变频器，汇川三相220V系列非标是在三相380V系列哪个功率的变频器的基础上改制的，为什么？汇川三相220V系列非标是在三相380V系列30kw功率的变频器的基础上改制的，因为三相220V，15kw系列非标的额定输出电流为52A, 三相380V系列30kw功率的变频器的额定输出电流也为60A,功率模块的电流范围是相当的。

5、变频器选用V/F控制时，确定电机磁通值的二个变频器相关参数是哪个？电机欠磁通运行和过磁通运行分别有哪些危害？变频器选用V/F控制时，确定电机磁通值的二个变频器相关参数是：F1组参数中F1-02额定电压、F1-04额定频率。

电机欠磁通运行：电机输出力矩不够。

电机过磁通运行：励磁电流发生严重畸变，电机发热厉害，因为电机铁损加大。

Winding3- phase:380 to 440 V ±6% Frequency:50 and 60 Hz Insulation class:F (155°C) Protection index:IP 54Electronic speed variation is applied tothe asynchronous motors of the MUL TI-HEcentrifugal pumps.The goal is to regulate the speed of the ACmotor by converting voltageand frequency of the mains inputs from 380to 440 V ±6% at 50 or 60 Hz into a threephase voltage system with variable frequencyand amplitude.The frequency converter then makes itpossible to control the speed of the motor.This simultaneous action on the frequencyand voltage is by means of two mainelements:- a diode rectiﬁer-a pulse width modulatinginverter (MLI).The rectiﬁer is a diode bridge. The ACvoltage conducted through the diode bridgeis converted into a rectiﬁed DC voltage.At this stage, to reﬁne the quality of the DCvoltage at the rectiﬁer output, a set ofcapacitors and coils eliminates any residualripple output from the rectiﬁer.In this way, we obtain a smooth DC voltagecalled the “DC bus”.With this development, the inverterdeﬁnitively adjusts the voltage at the outputof the variator to optimize the magnetizingof the motor. The set voltage at the inverterinput is converted again into a variablevoltage by acting as voltage pulses for avariable period of time via the transistors.This principle is referred to as pulse widthmodulation. These transistors are controlledby the micro-controller which activates ordeactivates them so as to vary the frequencyat the variator output.The transistors (IGBT: Insulated Gate BipolarTransistor) therefore operate by switching andact as switches to convert the DC voltageinto a variable voltage.The IGBT switching activation frequencycreates variable voltage and frequencymagnitudes.The frequency must be high toeliminate the noise produced bymagnetization (frequency inaudible to thehuman ear: 8 to 16 kHz).Pump code Nominal ﬂow in m 3/h (to 50 hz/2 pole )Number of stages Stainless S = 304 X = 316LE =O-rings : EPDM (WRAS/KTW)V =O-rings : VITON M13 = 1-phase Mode 1-3M2 = 1-phase Mode 2T = 3-phase 2 = 2 Pole2nd Generation inverterMode 1 / manual modeThe pump is installed in the same way as a MUL TI-H standard pump but offers the possibility of manually adjusting its speed and therefore working through a range of ﬂow.Pressure curves according to the needs of the installation.From the required Q/H point,the operating frequency can bedetermined by means of a curve plotter (see the following pages).MUL Ti-HE 402- SE - T/2- 2GRange Stainless 304Stainless 316L2/4/8/162/4/8Main partsMaterialsnon-aggressive aggressiveliquids liquids Pump casing Stainless 304Stainless 316L Impellers Stainless 304Stainless 316L Cells (stage)Stainless 304Stainless 316L Pump shaft Stainless 316L Stainless 316LMechanical seal Si carbide Tg carbide Carbon Carbon O-rings EPDM*Viton**PlugsStainless 316L Stainless 316L* T°110°C — **T°90°CNB: Stainless 304 (Z6CN18-9)or 316 L (Z2CND17-12)recommended materials offering high resistance to corrosion.

三向二位弹簧阀门多功能流量控制固定泵驱动说明书

3-Way, 2-Position Spool-Type Solenoid ValvesMulti-Functional Flow Control for Fixed Displacement Pumps3-Way, 2-Position Spool-Type Solenoid ValvesMulti-Functional Flow Control for Fixed Displacement PumpsThree-way, 2-position valves typically feature a three-porteddesign allowing flow paths inseveral different configurations, while only connecting two ports in any single position. The valve consists of a series of tapered cylinders with diameters that get smaller from top to bottom. It fits snuggly into a machined cavity port. A seal separates the two possible pathways, i.e., a supply port where pressure exists only when the valve is actuated and a tank port that acts as thehydraulic fluid reservoir.When work is being performed, a spool-type valve’s cylinder-inside-a-cylinder configuration slides back and forth, enabling the pressurized hydraulic fluid to flow to one or the other of the ports, depending upon the function required.Essentially, these valves allow design engineers to switch (divert) between two functions or to simply dump flow where it is not needed, thereby significantly increasing the types of work fixed displacement pumps can perform. Actuation can be achieved using solenoid coils, manual means, electronics or piloted using hydraulic oil. There are even complex systems that combine two or more actuation methods to optimize performance.Three-way, 2-position valves arefurther differentiated by their position at rest. The “normallyopen” design allows flow to travel from the pressure port when at rest; the “normally closed” design does not. How 3-Way, 2-Position Spool-TypeSolenoid Valves WorkFixed displacement pumps are a cost-effective solution for a variety of construction vehicles, from mini excavators, backhoes and dump trucks to larger hand-held snow blowers, skid-steer loaders and street sweepers. But since the amount of pressurized fluid delivered is driven by a constant speed motor, such pumps can only provide a consistent amount of flow, thereby limiting their functionality to less dynamic applications. Further, they do not allow for a no-flow scenario; when the machine and its motor are running, flow occurs whether or not it is actually needed to perform a specific hydraulic function.For engineers designing simple hydraulic circuits, adding one or more 3-way, 2-position spool-type solenoid valves to fixed displacement pump hydraulic systems can extend their capabilities for a nominal investment. This article will explain how such valves work while exploring some of the multi-functional applications made possible by these cleverly designed yet highly cost-effective valve solutions.Smaller-scale construction equipment using fixed displacement pumps can perform multi-directional functionality when used with 3-way, 2-position valves. These valves overcome the inherent limitations of constant flowby changing the flow path, for example, from up and down movement to lateral or tilt movement, as required bythe specific application. Such solutions are more economical and more compact than the typical alternative of doubling the size of the valve and pump to achieve greater flow.In applications where the circuit designer wants to divert flow from one leg of a circuitto another, several 3-way,2-position valves can be a cost-effective solution, emulatinga traditional directionalspool valve in a customizablemanifold setup. If dumpingis required and the systemdemands more than a singleadditional function, thesevalves can similarly be usedin tandem to meet specificfunctional and real estaterequirements.Three-way, 2-position valvesare also useful for applicationswhere flow is not constantlyrequired. Unlike variable flowpumps, fixed displacementpumps are not able to turnflow off except by stoppingthe motor and thereforeall equipment activity. Aconstruction equipment designteam can use these valves todump the oil back to the pump,constantly circulating thehydraulic fluid until it is againneeded to perform a function.No more deadheading andblowing out a pump becausethe uncompressible fluidhas no place to go and exertscontinual pressure on thesystem. Just flip a switch andthe circulating fluid does itsjob; switch it back, and thefluid recirculates through thesystem until it is again needed.Spool-type solenoid valveswork well in applications wherethe fluid is placed in and out ofa holding pattern as functionscease and then resume.However, for applicationssuch as bucket lifts whereloads need to be sustainedin position for a longer time,poppet-style solenoid valves¹are recommended.1 Poppet-style valves are a topic for sepa-rate discussion but essentially, they aredesigned with a spherical or conical, ratherthan a cylindrical shape, and are thereforecapable of achieving a tighter seal. Suchvalves are the preferred solution for load-holding applications.Typical ApplicationsAll 3-way, 2-position spool-type solenoid valves are not created equal. Here are some of the factors to be considered when comparing manufactured valves.• Flow and pressure requirements vary greatly by application, but from a design perspective, the higher the GPM and the PSI, the more versatile the valve.• From an operational perspective, it is essentialthat pressure closely follows actuation. Similarly, whenthe valve closes the response needs to be immediate. Valves that demonstrate low hysteresis provide predictable performance regardless of the direction of actuation. This characteristic facilitates the programming of functions while ensuring the end user is able to operate the equipment more intuitively.• Valves that integrate easily with a full range of hydraulic system components provide design engineers with the flexibility of modular build-outs, allowing designers to customize a manifold blockin as compact a design as possible. Modular designs economize on space and labor requirements, providing designers with greater flexibility as functional requirements evolve. • Ergonomic valveconfigurations optimizeequipment controllability.Quick actuation and precisealignment enable intuitiveoperator use. Ergonomicallydesigned hydraulic circuits giveOEMs a competitive edge byenabling intuitive operationthat improves safety andefficiency and lowers energyusage and operational costs forequipment users.• Maintenance andreplacement requirementsare another consideration. Thecoil on top of these valves iscontinually pushing or pullingso coil replacement needs to beeasy. The wires and connectorscan also wear due to corrosionor from being over-energizedwith current. Ideally, the valveshould be removable from themanifold with minimal effortand without removing theentire block assembly.• Temperature resistance is acritical performance factor forthe valve’s seal. Nitrile seals witha 250° F temperature thresholdare the industry standard. Coldtemperature resistance shouldalso be considered.Differentiating 3-Way, 2-Position ValvesBy partnering with the world leader in fully integrated hydraulic systems, OEM design engineers benefitfrom envelope-expanding performance thresholds and a depth of real-world experience with a vast range of hydraulic applications.• Ease of Maintenance - The modularity of Parker hydraulic system designs makes component replacementfast and easy. When the coil requires replacement in a Parker 3-way, 2-positionspool-type solenoid valve, all that is required is to remove a single coil nut. Then, without removing the valve from the manifold, the new coil canbe dropped into place before retightening the cartridge valve. • Superior SealPerformance - As partof the Parker Winner’sCircle series of hydrauliccomponents, these valvesfeature seals made from aproprietary compound thatcan sustain both higherand lower temperaturethresholds than the nitrileseal compounds used bymost valve manufacturers.Fluorocarbon seals withhigh-temperature thresholdsof 400°F are also available forequipment used in extremeenvironments.• Nominal Pressure DropDuring Flow - Althoughsome pressure loss duringflow is inevitable with any3-way, 2-position valveconfiguration, pressuredrop with the Parker designis considerably lower incomparison with othermanufactured valves due toa less restrictive flow path.• Exceptional ActuationResponse - Responsivenessat actuation is also superior,with a response time of only 50milliseconds.• Convenient On-LineProcurement - The Parker3-way, 2-position spool-typesolenoid valves are readilyavailable for on-line purchasein sizes -8 and -10. Additionalsizes are also availablethrough the Parker worldwidedistribution network.• Manual Override - Twomanual override functions helpto ensure worker safety.Perhaps most importantly,the Parker global footprintensures predictable availabilityand serviceability, includingdesign support to optimizeefficiency and field-basedtroubleshooting on everycontinent.Additional Valve Selection ConsiderationsJune 2019© 2019 Parker Hannifin Corporation Parker Hannifin CorporationHydraulic Cartridge Systems Division 595 Schelter Rd.Lincolnshire, IL 60069Ph: 847 955 /hcsStephen BruntonAbout ParkerAs the leading globalprovider of fully integrated hydraulic systems andadvanced hydromechanical and electromechanicalsubsystems and components, the Parker Hydraulic Systems Division is ideally positioned to provide the engineering expertise, precisionmanufacturing and reliable distribution network needed by construction equipment OEMs and their customers to meet the challenges of an increasingly competitiveglobal market.。

They appear in the text as follows:WARNING: This symbol is used to make you aware of an unsafe condition, hazard, or practice that can result in personal injury or death.CAUTION: This symbol is used to alert you to a condition or practice that can cause damage to the system or the vehicle, or both.NOTE: Is used to provide additional information that requires special attention by the technician.Product Safety WarningsWARNING:EMP cannot anticipate every possible circumstance that might involve a potential hazard. The safety messages in this document, in related manuals, and on the product are therefore not all inclusive. If a tool, procedure, work method, or operating technique that is not specifically recommended by EMP is used, you must satisfy yourself that it is safe for you and for others. You should ensure that the product will not be damaged or be made unsafe by the operation, maintenance, or repair procedures that you choose.WARNING:Ensure that all safety messages and information messages are read and understood before installation, maintenance, or any repairs are performed. The person servicing may be unfamiliar with many of the systems on the vehicle. It is important to use caution when service work is performed. Knowledge of the vehicle system and operation are important before the removal or disassembly of any component.WARNING: Make sure the equipment cannot move while being serviced. If on vehicle, ensure the vehicle is in neutral, the parking brake is set, and the wheels are blocked before doing any work or diagnostic procedures on the EMP component, system, or vehicle.WARNING: Disconnect the power supply, main negative battery cable, and/or switch off the battery disconnect switch before installation or servicing.WARNING: Use extreme caution when working on systems under pressure (i.e. coolant, hydraulic fluids, air, fire suppression, etc…)WARNING: Make sure the work area is ventilated and well lit.WARNING: Make sure charged fire extinguishers are in the work area.WARNING: Reinstall all safety guards, shields, and covers after servicing the equipment or vehicle.WARNING:Make sure all tools, parts, and service equipment are removed from the equipment, engine compartment, and/or vehicle after all work is done.WARNING:Ensure that all system power and ground connection points are properly secured. Improper attachments at any point of the equipment or vehicle system power and ground can result in loose connections which can damage electronic components on EMP components and systems and will void EMP warranty.Purpose PurposeThe purpose of this Quick Start Guide is to present information related to the pump’s dimensions, electrical specifications, coolant guidelines, recommended plumbing, and routine maintenance.NOTE: For production applications of this product, the full installation specifications must be met. Contact EMP to request documentation.SpecificationsImportant Note:Images do not represent acceptable mounting positions. They are for dimensional reference only.DimensionsFigure 1Hole Locations/Bolt SpacingFigure 2ElectricalTable 1Operating Voltage (DC) Rated Output Min Max12V Models 13.5V nominal 9V 16V24V Models 27.0V nominal 18V 32VIdentification IdentificationThe product identification labels are attached to the controller housing next to the electrical interface of the pump. The pump hardware part and serial numbers are located on the upper label. The lower label identifies the Programmed Assembly number and the associated control software as the pump leaves the manufacturing facility.Figure 3Label DetailsFigure 4InstallationProper Pump OrientationFor vertical, horizontal, and dual orientation specific pumps, orientations are tied to the individual pump part numbers. The part number includes the motor stator for the appropriate voltage, the controller circuit board, and the vent port configuration.The Dual Orientation pumps cannot be mounted at any arbitrary angle (i.e. 45 degrees off axis) for a list of part numbers with dual orientation. Standard Service pumps can use either the Vertical or Horizontal Orientations for list of part numbers with vertical and horizontal orientations.Figure 5 - Vertical Pump Orientation – (Pump is shown at -5 degrees nominal angle)Figure 6 - Horizontal Pump Orientation – (Pump is shown at -5 degrees nominal angle)Incorrect Pump Orientation and ReasonsThe WP29 and WP32 contain a mechanical seal; 0.1cubic centimeters per hour may weep past the seal as a part of normal operation. To properly collect the weepage pump orientation is important. Too steep of an angle will not allow the fluid to collect in the weep pocket and evaporate off and the pump may appear to be leaking when in fact it is operating as designed. An incorrect mounting angle may also result in too much fluid being retained in the weep pocket resulting in bearing contamination and reduced service life. See Figure 7 for incorrect pump orientation and reasons. The WP29 and WP32 are marked with orientation labels. (See Figure 8 and Figure 9 below).Figure 7 - Incorrect Pump Orientation and ReasonsFigure 8 - Vertical Pump Orientation LabelFigure 9 - Horizontal Pump Orientation LabelPump Inlet must be plumbed using 25mm (1.0 inch)diameter hose and/or thin walled tubing from thefluid supply to the pump inlet.A restriction in the inlet plumbing is allowed as longas the flow diameter is not less than 17mm (0.75inch) and does not exceed 25mm (1.0 inch) inlength.CAUTION: Localized high spots in theplumbing will cause air to be trapped in the pumpcausing the pump to be air locked. The result ofair trapped in the pump is loss of prime and nofluid moving resulting in water seal damage orpotential system component damage.Figure 10 CAUTION: EMP warranty does not coverseal damage due to low lubrication.Hose ClampsWhen making the inlet and outlet hose connections to the pump it is strongly recommended to use SAE20CT worm drive type hose clamps. Torque worm drive clamps to 45 in-lbs per SAE J1508. Spring type clamps are not recommended.Pump MountingMounting ScrewsMounting screws used should be M8 x 1.25 screws (quantity = 4). These must have a minimum thread engagement of 0.50 inch (12.7 mm) and be tightened to a torque of 15 ft-lb (20N-m).CAUTION: The mounting holes are tapped to a depth of 0.59 inches (15mm). Be aware of the bracket thickness when selecting the fastener length to ensure that the fastener will not bottom out in the pump housing.Bracket Mounting• Hard Mount pump on a solid bracket• Bracket material should be .187 inch minimum thickness• Bracket natural frequency must be above 150 Hz with pump mounted.• Bracket should shield weep holes if possible• Locate the pump away from external heat sources and direct road sprayCAUTION: Using isolators may cause pump damage. If using the isolators, it is the installer’s responsibility to Verify isolator size for pump weight and operating conditions with isolator vendor to ensure correct isolator.ElectricalElectricalConnector Pin-outsFigure 11 - Controller ConnectorsMating ConnectorsThe mating connectors and pins are available from your EMP distributor in kit 1370001077 for the 6 pin and 1370001078 for the 4 pin connector.Table 26 Pin Connector Deutsch Part Numbers 4 Pin Connector Deutsch Part NumbersDescription Part Number Description Part Number Socket Pins 0462-201-20141 Socket Pins 0462-203-12141 Connector Body DTM06-6S Connector Body DTP06-4S Wedge Lock WM-6SWedge lock WP-4S Plugs0413-204-2005Plugs114017NOTE: If CAN or Serial TTL control is not used the 6 pin DTM connector must be blocked off to prevent entry of water or dirt which will result in damage to the pump. A block off plug is supplied with the pump.Figure 12 - Sample Wiring Schematic – Harness 3170001029 is available for purchaseNOTE: These represent the controller connectors – not the mating harness connectors.NOTE: Addressing and motor status message information can be found in our J1939 Motor Control Document, 99800010681 – CANH2 – CAN SHIELD3 – SERIAL GND4 – SERIAL TX5 – SERIAL RX6 – CANL1 – TEMP INPUT OR CAN ADDRESS2 – GND3 – BATT4 - IGNITIONElectricalIgnition InputPin 4 on the 4-pin connector is used for ignition. This should be tied to a switched power supply, separate from the power and ground pins.The ignition input must be used to turn the pump “on” and “off”. This is to ensure that the fault code history and warranty data is captured in the pump’s memory.Table 3 - Vehicle Ignition ParametersVehicle Ignition ParametersV in Limits 9V minimum32V maximumV in Nominal 13.5V (12V system)27V (24V system)Ignition Current ***********4mA @ 27VWire Sizing•For complete connector body sealing the ignition wire should be 16ga minimum and thepower and ground wires should be 12ga minimum.•Wire jacket diameter must be compatible with seal requirements. Recommended Wiring Practices •Wiring or electrical harness must not rub on sharp edges.•The electrical harness should not be stressed at connections. Wires pulling on connectorscan compromise the connector body seal andpossibly create a water intrusion event.•The voltage drop between the battery and the pump should not exceed 5% of the ratedbattery voltage. This should be verified at thepump’s maximum current draw. Wiring orelectrical harness must not rub or makecontact with a hot surface. There should be 5"minimum clearance from the exhaust. •Wiring or electrical harness should be supported at least every 18" to 20".•To avoid possible fire or shock, do not pinch any wiring or electrical harnesses. •Incorporate Drip Loops into wiring designs.The pump connectors are environmentallysealed. However, good wire management canhelp ensure a good seal over the life of theproduct. Drip loops collect water and shed itaway from connector.•The use of Dielectric Grease such as Dow Corning DC-4 is acceptable as long as theconnection is mated directly after greaseapplication to prevent dirt from being capturedby the grease.FluidsFluidsApproved CoolantsBased on field testing and experience, the WP29/WP32 is compatible with the following coolant types:1. Ethylene Glycol2. HOAT ( Hybrid Organic Acid Technology)3. OAT (Organic Acid Technology)4. Propylene GlycolNOTE: Use distilled water to dilute coolant or use pre-mix coolant.Supplementary Coolant Additives (SCA)Coolant additives are allowed with the WP29/WP32 water pump. The additive must be compatible with the base coolant and all contact surfaces of the pump. The additive concentration must be within the additive manufacturer’s specification. Damage to the pump or the system will not be warranted if the additive is not compatible with the base coolant or the concentration is outside manufacturer recommendations.CAUTION: Use of “Stop Leak” style system additives is not approved.CAUTION: Mixing of coolants can cause problems with the cooling system. Fluids can interact resulting in damage to the cooling system and pump. Coolant Fill ProcedureEach time the cooling system is drained, caution must be taken to ensure the system is refilled properly to prevent running the pump in a dry state.1. Install pump and piping according toinstallation instructions.2. Ensure flow path is open through the entiresystem.3. Fill the system with coolant such that thepump is filled with coolant and there is coolantwithout air pockets in the piping leading to thepump.4. Run the pump at high speed, ensuring coolantlevels are topped off as air is pushed out ofthe system. Do not allow the pump coolantsupply to become empty.5. Verify coolant flow in the surge tank or heatexchanger to ensure pump operation. If noflow is detected, turn the pump off andevacuate system air.CAUTION: Do not run the pump without fluid present. If run dry even for a short period the seal will be damaged.CAUTION: Pump may start running upon connection of power, ground and ignition. Do not make electrical connections until pump and system are filled with coolant.Maintenance and ServiceRoutine Maintenance ScheduleFrequency ActionWhen checking/filling vehicle fluids Ensure fluid levels are correct. Low coolant can cause a pump seal failure.Every engine oil change Inspect cooling system for leaks. Sample coolant and check to ensure coolant meets minimum coolant quality requirements. Before removing the pump, evaluate the leak using the methods outlined in the physical inspection of this document.Every three months or more often if conditions are harsh* Visually inspect exterior of pump and ensure weep holes are not clogged by debris. Check wires for wear or frayed insulation. Ensure all electrical connections are tight.Annually+ Ensure connections aretightened to proper torquerating. Ensure all wires andpin connections are intact.Inspect support structure forany damage or loosehardware.+ Inspections should also be conducted after any service to the unit.

The ball stem, ball and lower trunnion shaft are one piece.1. USE:1.1 Life of valve can be maximized if the valve is used within the rated range, in accordance with pressure, temperature, andcorrosion data.1.2 As shipped from the factory, valves contain silicone-free lubricant. If silicone free lubricate is unacceptable for yourapplication, you may disassemble the valve and wash the parts in solvent. The valves may also be ordered from thefactory either degreased and bagged or oxygen cleaned.2. MANUAL OPERATION:2.1 To change flow pattern of the valve, turn the handle ¼ turn (90 degrees).2.2 Both T port and L port are available.2.3 Flow path is clearly marked on the stem and handle washer.3. AUTOMATED OPERATION:3.1 Valves with actuators should be checked for valve stem alignment. Angular or linear misalignment will result in highoperational torque and unnecessary wear on the stem seal.4. GENERAL INFORMATION FOR ON-SITE INSTALLATION:4.1 The valve may be fitted in any position on the pipeline.4.2 To prevent damage to the seats and ball surface, the pipeline must be flushed, free of dirt, burrs, and welding residuesbefore installing the valve.5. GENERAL SAFETY PRECAUTIONS BEFORE DISASSEMBLING & CLEANING THE VALVE:CAUTION, FLUIDS CAN BE TRAPPED IN THE BODY OF THE VALVE POSSIBILY UNDER HIGH PRESSURE.WARNINGFOR YOUR SAFETY, IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS BE TAKEN BEFORE REMOVAL OF THE VALVE FROM THE LINE OR ANY DISASSEMBLY.5.1If the valve has been used to control hazardous media, it must be decontaminated before disassembly.It is recommended that the following steps are taken for safe removal and reassembly.5.2. Wear protective clothing and equipment when working with potentially harmful fluids.5.3. Depressurize the line and cycle the valve as follows:5.4. Place the valve in a mid-port position and drain the line.5.5. Cycle the valve to relieve residual pressure in the body cavity before removal from theline.5.6. Allow valve to cool if valve is used in high temperature applications.5.7. After removal and before any disassembly, cycle the valve again several times to relieveextra trapped fluids or gases in the body section.6. DISASSEMBLING, CLEANING AND REBUILDING THE VALVE:Caution When replacing Teflon parts, please replace all seats, joint gaskets,Gland packing and stem O-ring.6.1Carefully mark the orientation of the top cover to the body and each end cap to the body. This will make reassembly of the valve more accurate.6.2 Loosen and remove handle stop bolt (21) & bolt nut (22). Loose set screw in the side of the handle. Then remove handlescrew (19), lift off handle. For valves 2-/12”thru 6” remove handle screw (19), remove indicator plate (18), and lift off handle (16) and handle hub (17) together.6.3 Remove gland nuts (28) then remove gland bolts (27) Note on the 6” valve only the Belleville washers (14) are on the packing gland bolts.
