ORV are 3-way industrial valves for maintaining a constant oil temperature in gas compressor systems, by mixing hot and cold oil in the lubricating system of e.g. screw or turbo type compressors.The ORV valves are with few components and with extended cylindrical connections, to ensure ease of installation and service.Features• Stainless steel nickel plated thermostaticelement.• Butt-weld (DIN, ANSI) or socket weld (SOC)connection.• No manual adjustment.• Plug and Play design.• Optimised flow characteristics.• Sturdy construction.• High resistance against vibrations or shock.• Can be mounted in any direction.• Service friendly. Easy to dismantle and service when required.• Classification: DNV, CRN, BV, EAC etc.To get an updated list of certification on the products please contact your local Danfoss Sales Company.Technical data Oils:Applicable to all common refrigeration oils.Refrigerants:Applicable to HC, HCFC, HFC, R717 (Ammonia)and R744 (CO2).For further information please refer to installationinstruction for ORV.Temperature range:Minimum operating temperature:≥ –10°C (+14°F)Max. temperature limit based on the element temperature settings:Types Max limit43°C / 110°F77°C / 170°F49°C / 120°F82°C / 180°F60°C / 140°F93°C / 200°F77°C / 170°F110°C / 230°FPressure range:The valves are designed for a max.working pressure of 40 bar g (580 psig)Design IdentificationConnectionsAvailable with the following connections:• Butt weld DIN (EN 10220),DN 25-80 (1-3 in.)• Butt weld ANSI (B 36.10 Schedule 80),DN 25 - 40 (1 - 1½ in.)• Butt weld ANSI (B 36.10 Schedule 40),DN 50 - 80 (2 - 3 in.)• Socket Weld (ANSI B 16.11),DN 25 - 50 (1 - 2 in.)HousingMade of special, cold resistant steel approved forlow temperature operations.InstallationInstallation of the valve depends on the way itshould operate.Pressure Equipment Directive (PED)ORV valves are approved according to theEuropean standard specified in the PressureEquipment Directive and are CE marked.For further details / restrictions - see InstallationInstruction.FunctionMixing operationORV valve can work as a mixing or diverting valve. The ORV temperature regulating valve utilises the high coefficient of thermal expansion of wax to create the internal movementnecessary to have a cold and a hot inlet mixing to a common outlet. The outlet temperature will correspond to the nominal temperature of the thermostatic element.The valve house has three ports:• Port A is used for the common outlet • Port B is for the hot inlet •Port C is for the cold inletWhen the compressor unit is cold at start up, the thermostatic element will be contracted to let the full flow from port B pass until the nominal temperature (minus 5 K / 10°F ) is reached (fig. 1.1). The thermostatic element will then begin to extract to let the outlet become a mixture of hot and cold oil.When the nominal temperature is reached, the element is positioned in approximately half open position (fig. 1.2). If the temperature is reaching approximately the nominal temperature plus 5 K, the thermostatic element has been extracted to its fully open position (fig. 1.3). In this position the oil temperature will only come from the cold inlet port (C) from oil cooler.From figure 1, it can be seen how the sleeve on the element is sliding in a vertical movement. The thermostatic element is kept in position by a spring.Diverting operationDiverting operation is similar to the mixing operation. It is carried out with separation in to two of the fluid with single temperature. Due to that the temperature on the inlet is very stable fact the regulation is very smooth. The inlet temperature would correspond to the nominaltemperature of the thermostatic element.The valve house has three ports:• Port A is used for the common inlet • Port B is for the cold outlet • Port C is for the warm outletThe diverting operation otherwise is similar to the mixing operation.Application examplesExample of the system with ORV for diverting operationCapacitiesSI unitsSelection exampleOil type: Grade 68Required flow: 17 m3/hNominal oil temperature: 49°CPipe dimension: 40 mmThe upper left curve shows the viscosity of different grades of oil as a function of the temperature. The viscosity is continued into the upper right curve where the 17 m3/h must be found. The line is drawn vertically downwards into the capacity table for the ORV valve models.As shown two selections can be made:Either ORV 40 H2 with pressure drop at approx. 0.56 bar or ORV 50 H2 with pressure drop at 0.42 bar.The final selection will depend on the available pressures in the system. If the pressures are low (or can be low at certain loads) the ORV 50 H2 might be preferred. If the pressures are constantly available the pipe dimension may be taken into account and the ORV 40 H2might be preferred.CapacitiesUS unitsSelection exampleOil type: Grade 68Required flow: 75 USgal/min.Nominal oil temperature: 120°FPipe dimension: 1½”The upper left curve shows the viscosity of different grades of oil as a function of the temperature.

The line is drawn vertically downwards into the capacity table for the ORV valve models.As shown two selections can be made:Either- ORV 1½H2 with pressure drop 8.2 psi or- ORV 2”H2 with pressure drop 6.2 psiThe final selection will depend on the available pressures in the system. If the pressures are low (or can be low at certain loads) the ORV 2" H2 might be preferred.

We recommend that you read this manual carefully before commencing any work .Danfoss is not responsible or liable for any damage caused by failure to comply with the instructions in this manual and/or due to incorrect installation, operation and mainte-nance of MCHEs .All personnel being responsible for operation and maintenance of theeat exchanger unit must read and fully understand these instruc-tions before:• Transportation of the MCHE unit • Lifting the unit• Installing the MCHE unit •S ervicing the MCHE unit • Maintaining the MVHe unit•1.2 Gener alI ndicates something to be noted by thereaderI ndicates a situation which will or could result in personal injury and/or damage to the MCHE1. IntroductionSevice guide | Application, Installation and Maintenance Manual MCHE4 |AX292455807588en-000101 | 01.20192. Storage and workingenvironments• Microchannel heat exchangers should bestored indoors in a dry and clean environ-ment .• The storage temperature range is -40 °C to 121°C (-40°F to 250°F) .•Metal chips, and/or copper or steel dust can cause galvanic corrosion, so storage and installation areas must remain clean and separate from machining or welding areas . Use separate tools and/or keep tools clean .•To minimize potential damage, we recom-mend that you keep MCHEs in their original packaging until they are installed in the air conditioning or refrigeration equipment . •Improper storage and stacking of MCHEs can cause premature corrosion or deforma-tion and will reduce MCHE’s life . Extra care should be taken when storing MCHEs!• Refrigerants used in MCHE shall comply with AHRI Standard 700 .•The maximum operating pressure shall not exceed the value shown on the Label of MCHE .2.1 Stor a ge2.2 H a ndlingCompared to tube & fin coils, microchannel heat exchangers are relatively light, the fins are harder to bend and they are less likely to cut fingers . The combination of these features makes MCHEs easier to handle than tube & fin coils . However, the overall coil assembly is made of soft alu-minum, so it is susceptible to deformation (Fig .1)Fig . 1 Handling attentions2.3 Bending procedureThe same bending machines can be used for MCHE and tube & fin heat exchangers . In order to optimize costs associated with shipping and packaging, we recommend that MCHEs be shipped flat and formed at the customer’s location .Bending Radius:The minimum bend radius required to achieve acceptable manufacturing yields is a function of the microchannel tube, fin, and alloy, the overall capabilities of the bending equipment including, fixturing, bending speed and bending length .NOTE: Conducting trial bending runs of thespecific coil and configuration are recommended to verify . In general, tighter radius, thicker tubes and longer bend lines are harder to bend . Use a larger radius if possible .Recommended minimum bending radii (as determined by factory tests under favorable conditions) are shown in Table 1 for different microchannel tubes and fins . Consult with Danfoss for the tubes not listed . Do notarbitrarily extrapolate or interpolate the values .•Never lift a MCHE by the inlet and outlet tubes as it might result in dimensional deviation or worse yet, the initiation of a crack that can later result in a leak .• Do not hit or drop MCHE on edges . The MCHE is constructed of soft aluminum therefore, dropping, striking, placing heavy objects on top of, or stepping on any part of the heat exchanger will likely cause a deformation . If the coil becomes slightly deformed or bowed, it is possible to flatten them back out by laying them concave side down on a flat hard surface and applying pressure via a large heavy flat plate (say 3-4 square feet of ½” non-metallic sheet, such as plywood or plastic, with a couple of handles attached) . This procedure works for bowed coils with flush fins, but not for local fin protrusions .Table 1Service guide | Application, Installation and Maintenance Manual MCHE5AX292455807588en-000101 | 01.2019 |Consider the following during bending:• MCHEs are constructed of soft aluminumand are susceptible to deformation during handling . Prior to bending operation, make sure the MCHE is flat, square and undam-aged . Consider a sizing operation to ensure this .• Make sure the coils are loaded into thebender in a way that keeps them flat square and undamaged . • Keep the flat tubes perpendicular to thespindle while bending the coil .• Clamp the coil during the bending process,being careful not to crush it . • Slower bending speeds will often yieldbetter results .• Vertical spindle bending machines are oftenset up so that the microchannel coil ends up sliding along the table with all its weight supported by the header ends and/or the bottom dead tube .During the bending operation, do not let one end of the coil become cantilevered off the edge the table, because this can cause the coil to droop with the tubes being non-perpendicular to the spindle, resulting in corkscrewing or reduced bend quality and/or consistency . Note that with some benders, a portion of the supporting table will drop down during bending, creating opportunities for cantilever loads and improper bending .•Bending multi-bend coils on a horizontal spindle bender can cause cantilevered loads resulting from the dead weight of the unsupported bent legs . As an example, a coil with three (3) bends, depending on fixturing, may result in the load of the first 75% of the coil being transferred into the remaining coil leg, possibly causing poor bend quality and/or permanent deforma tion . Bending challenges are greater with MCHE’s than similar fin and tube coils, requiring proper fixturing .3. Inst a ll a tion 3.1 Pass arrangementCarefully identify the locations of the inlet andoutlet tubes . Microchannel condensers is often designed with multiple passages (parallel flow) that have fewer tubes in each successive pass (Fig . 2)Danfoss MCHEs include a small notch in both headers to indicate that this is the bottom of the heat exchanger . Additionally, a product label is placed on the outermost tube (unless specified elsewhere by the customer), indicating the top of the heat exchanger .Incorrectly connecting the inlet and outlet tubes of a MCHE will likely result in excessive refrige-rant side pressure drop and poor heat transfer .Fig . 2 MCHE passes distribution3.2 Fan location and sizeAir distribution may have an influence on the performance of the MCHE . For good air distribu-tion choosing a fan with proper fan diameter and keeping a constant distance between the coil and the fan is desirable . We recommend selecting a fan diameter that is as close as possible to the smallest of MCHE height and length . The distance between MCHE and fan is )recommended to be at least 15 times the width/depth of MCHE coil when possible (Fig .3) .Fig . 3 Fan location and sizeSevice guide | Application, Installation and Maintenance Manual MCHE6 |AX292455807588en-000101 | 01.20193.3 Coil mounting against thermal expan- sionThermal expansion of aluminum is higher than most other metals . Frequent thermally induced stress could shorten the life of the micro channel heat exchanger (Fig .4)Fig . 4 Coil mounting for MCHETo avoid the risk of thermal expansion, a micro channel heat exchanger must be mounted with brackets that allow some flexibility of movement . Mounting methods as indicated in Figures 5a and 5b are recommended .Fig . 5b Mounting by end plateInlet/outlet connections are not designed to be used as handles, support mating tubes, resist with mating tubes during assembly, etc . In particular:• not exposed to stress/tension . (Fig .6)aluminum inlet/outlet tubes and/orforcing is required during installation .Fig .6 Inlet/Outlet connection attentionsService guide | Application, Installation and Maintenance Manual MCHE7AX292455807588en-000101 | 01.2019 |Plastic heat shrink tubing prevents galvanic corrosion in the MCHE’s copper to aluminum joint by keeping moisture from entering the area . A minimum of 70mm length from the Cu/Al joint to the connection point is required to protect the Cu-Al brazing joint and plastic shrink tube from excessive heat during the brazing process . When brazing copper piping to the MCHE, it is recom-mended to use dry nitrogen purging along with a heat sink and/or wrapping the copper stub tube with a wet cloth to protect the Cu/Al joint and heat shrink tubing from excessive heat . This also applies to microchannel heat exchangers with aluminum inlet/outlet tubes . Depending on the location of the connections relative to the heat exchanger, a heat shield may be required to protect the MCHE’s tubes and fins from the brazing torch . The recommended pipe length “L” after the brazing joint should be greater than or equal to 70mm as shown in the picture below (Fig .7) .Fig . 7 Recommended length of inlet/outletconnections3.4 Elimination of gapsTo maximize heat transfer performance, gaps should be eliminated on both sides of the face of the MCHE . Gaps should also be eliminated on the top, bottom and sides of the MCHE so that all fan induced air is directed over the coil surface . This can be accomplished with sealing strips as shown in Fig . 8 .Fig . 8 Typical installation3.5 Prevention of galvanic corrosion Aluminum is a chemically reactive metal and will corrode when combined with most metals that are used today in industrial manufacturing . To avoid any galvanic corrosion, it is necessary to separate Al and other metals . The best way to prevent galvanic corrosion is to use plastic/rubber/foam as a means to isolate the aluminum coil from dissimilar metals (Fig 8)Sevice guide | Application, Installation and Maintenance Manual MCHE8 |AX292455807588en-000101 | 01.20193.6 Vibr a tionVibration that exceeds a specific range maycause the failure of MCHE . To avoid failure due to vibration:•Make sure vibration level meet require-ments as in table 2 .Table 2 The allowable vibration rangesService guide | Application, Installation and Maintenance Manual MCHE9AX292455807588en-000101 | 01.2019 |5. Co a tingCoating of a heat exchanger could increase corrosion resistance in certain applications and/or environmental conditions such as coastal or industrial areas, as well as situations with stagnant water or extreme wet conditions . Danfoss approved coating systems provide a controlled process for the cleaning, rinsing, and the application of the coating material with full and even coverage . Untested coating systems may not adhere properly to the aluminum surface due to the flux residue left on thealuminum surface after brazing . In addition, any small area not covered by the coating couldpotentially pose a risk of failure due to corrosion . Thermal performance may also be reduced by improper application of the coating resulting in clogging or bridging between the fin and louversWARNINGSField applied coatings are not recommended for brazed aluminum MicroChannel heat exchang-ers .Danfoss MicroChannel heat exchangers must NOT be coated using any other coating, but the ones specifically approved by Danfoss, such as certain qualified e-coating (epoxy based electrophoretic coating) suppliers or similar high-quality coating technologies . Coating of a coil using a supplier or coating process notapproved by Danfoss voids the product warranty . It may also reduce the lifetime and/or the performance of the MicroChannel heat exchanger . Consult your Danfoss Sales &Application representative for more information .6. M a inten a nceFrequent servicing is essential to maintainingthe required MCHE performance . For everyinstalled Danfoss MCHE, service records must be documented .CAUTIONPrior to servicing the MCHE, be sure to discon-nect the power supply and use lock-outmethods to prevent the power from acciden-tally being turned on .6.1 FiltersDanfoss recommends the use of air filters on the frontal face of the MCHE to lower the deposition of rain water and other contaminants that can collect on the surface of the tubes .6.2 Shut down periodsDuring periods when the MCHE is not operated for longer than a week, the MCHE must be completely cleaned following the cleaningprocedure . This practice must also be performed during short shut-down periods where corrosive deposits accumulate on the MCHE .6.3 Cleaning procedureRelative to tube & fin heat exchangers, Micro-Channel heat exchanger coils tend to accumu-late more dirt on the surface of the coil and less dirt inside the coil, making them easier to clean . Follow the steps below for proper cleaning:Step 1: Remove surface debrisRemove surface dirt, leaves, fibers, etc . with a vacuum cleaner (preferably with a brush or other soft attachment rather than a metal tube),compressed air blown from the inside out, and/or a soft bristle (not wire!) brush . Do not impact or scrape the coil with the vacuum tube, air nozzle, etc .Step 2: RinseRinse only with water . Do not use any chemicals (including those advertised as coil cleaners) to clean MicroChannel heat exchangers, as they may cause corrosion .Hose the MCHE off gently, preferably from the inside-out and top to bottom, running the water through every fin passage until it comes outclean . The fins of MicroChannel coils are stronger than traditional tube & fin coil fins but still need to be handled with care . Do not hit the coil with the hose . We recommend placing your thumb over the end of the hose rather than using the end of the nozzle to obtain a gentler spray and reduce the possibility of impact damage .We do not recommend using a pressure washer to clean the coil due to the possibility of damage .Warranty claims related to cleaning damage, especially from pressure washers, or corrosion resulting from chemical coil cleaners, will NOT be honored .Step 3: Blow dryDepending on the installation and fin geometry, MicroChannel heat exchangers could possibly retain more water compared to traditional tube & fin coils . It is advised to blow off or vacuum out the residual water from the coil to speed up drying and prevent pooling .Danfoss recommends a quarterly cleaning of the coils, as the minimum . The cleaning frequency should be increased depending on the level of dirt/dust accumulation and the environment (e .g ., coastal areas with chlorides and salts) orindustrial areas with aggressive substances .Danfoss MicroChannel Heat Exchangers (Jia Xing) Co ., Ltd .No . 8, Sangdelan Road, Wuyuan Street,Haiyan, Zhejiang Province314300 P .R .

November 2010Application notesA p p l i c a t i o n n o t e sA counterbalance valve provides several functions:· Free flow in one direction.· Leak-free load holding.· Protection against hydraulic line failure.· Protection against pressure shocks caused by external forces or overrunning loads · Cavitation-free motion control to match speed to pump flow when a load could cause loss of control of an actuator (cylinder or motor).·Smooth, modulated motion control when the directional valve is suddenly closed.COUNTERBALANCE VALVESCounterbalance valvesMotion control valves, also referred to as load holding valves, are used to control the motion of a load in the following ways:· Prevent a load from dropping in case of hose or tube failure.· Prevent a load from drifting caused by directional control valve spool leakage.·Provide smooth, modulated motion when the load is in a lowering or run-away mode.·Provide smooth, modulated motion when the directional control valve is suddenly closed.There are two basic types of motion control valves:·Pilot-operated, or pilot-to-open check valves will satisfy the first two of the above requirements.·Counterbalance valves will satisfy all four of the above requirements.MOTION CONTROL VALVESCounterbalance valves9.4520L0588 ? Rev DB ? November 2010Application notesApplication notesCounterbalance valves will positively hold a pressurized load and willcontrol the motion of the load based on application of a pressure signal to the pilot port. Counterbalance valves are available as individual cartridges or standard cartridge-in-body (CIB)packages.Individual cartridge counterbalance valveA typical circuit application for acounterbalance valve contains a pump, directional control valve, and an actuator. Without a counterbalance valve the load will drift down due to spool leakage if the directional control valve is centered with the load raised. Additionally there is no protection against the load dropping in the event of hydraulic line failure.Circuit without a counterbalance valveCircuit with a counterbalance valveAdding a counterbalance valve controls motion and provides protection against hose or tube failure. In this circuit, moving the directional control valve to the left causes the cylinder to extend, raising the load with free flow going through the check valve portion of the counterbalance valve. When thedirectional control valve is centered, the counterbalance valve will prevent leakage and lock the load in position. Moving the directional control valve to the right sends flow/pressure to the rod end of the cylinder. This pressure also acts to pilot open the counterbalance valve and allows the load to be lowered. Should the load cause the cylinder to run away from the pump, pilot pressure to the counterbalance valve will decrease and the counterbalance valve willmodulate to match the cylinder speed to the pump flow.COUNTERBALANCE VALVES (continued)C o u n t e r b a l a n c e v a l v e s9.5520L0588 ? Rev DB ? November 2010Application notesA p p l i c a t i o n n o t e sThe pressure required to pilot open the counterbalance valve can be calculated as follows:P = (Ps ? Ab) - W (load retracts cylinder) (Ab ? R) + ArP = (Ps ? Ar) - W (load extends cylinder) (Ar ? R) + Ab W = LoadPs = Counterbalance valve relief setting; see below for more information Ab = Cylinder bore area Ar = Cylinder rod area R = Counterbalance valve pilot ratio; see below for more informationNote that these equations are idealized and do not consider any backpressure in the circuit, which is additive to the pressure required to pilot open the check valve.Some additional guideline s for counterbalance valve applications:·Specify the counterbalance valve relief setting high enough to stop any motion (flow) at the maximum expected actuatorpressure. Generally it is recommended to use a setting of 1.3 multiplied by the maximum load pressure.·Use low pilot ratios (3:1 and 4.5:1) for applications where loads may vary widely. Low pilot ratios require higher pilot pressure and are less efficient but provide stable, precise control for varying loads.·Use high pilot ratios (8:1 and 10:1) for applications where loads are relativelyconstant. High pilot ratio valves require lower pilot pressure, have faster response, and are more efficient, but lack stability and precision in response to varying loads.·Do not oversize counterbalance valves. There is no pressure drop operating limit forcounterbalance valves and in fact some pressure drop is required to maintain valve operation.·Locate counterbalance valves at or near the actuator to provide maximum load holding protection in the event of hydraulic line failure.·Do not use counterbalance valves with closed-center directional control valves. Pressure trapped between the directional control valve and the actuator can pilot the counterbalance valve open and result in undesired load motion.·Do not use counterbalance valves with tandem-center directional control valves.Backpressure in the system can prevent the counterbalance valve from opening.COUNTERBALANCE VALVES (continued)Counterbalance valves9.6520L0588 ?
