It automatically adjusts pump flow in response to a remote pressure signal and maintains outlet pressurePVE with PressureCompensator Arrangedfor Remote Control,“D”Option or“J”OptionExactly the same as the“A”(pressure compensa-tion option)except themachine operator is able tochange the compensatorsetting through the use ofa remote pilot relief valve.Note:Graphic symbolsshown with externalvalve(s)and

Control“B”OptionSee pages19-20for other details and dimensions.PVE19/21Remote Adjustment Compensator Control“D”Option22Unloading Valve Control–“E”OptionWith the unloading valve control the variable pump will unload at a preset pressure.The pump will maintain this no flow,low pressure(approximately14bar(200psi))standby condition,until system pressure drops to about 85%of the preset unloading pressure.The pump will then return on stroke and provide full flow until the preset unloading pressure is reached again. With this control,an efficient accumulator charging circuit is obtained. The pump will provide full flow to fill the accumulator until the maximum charging pressure is reached.The pump then goes to a standby condition until the accumulator pressure drops to85%of the desired maximum. The accumulator is then recharged as the cycle starts over again.A separate right angle check valve must be provided to maintain the accumulator hydraulic charge and prevent back flow when the pumpis unloaded.The check valve’s internal leakage must not exceed five drops per minute.The control port must be connectedto system pressure, downstream of the check valve.Adjustment rangePVE19100-210bar(1500-3000psi)PVE21100-186bar(1500-2700psi)Cut-in pressure is85%of unloading pressure,minimum.Setting Pressures1.Back out accumulatorunloading pressureadjustment screw tobelow desired unloadingpressure.2.Adjust desired standbypressure.3.Set accumulatorpressure by screwingin the accumulatorunloading adjustmentscrew.Accumulatorrecharge(cut-in)pressure is a functionof the maximumaccumulator pressureand is not adjustable.4.Check pressuresettings and re-adjust ifnecessary.2324Shaft OptionsPVE19/216.376.35(0.251)(0.250)No.SAE No.No.04Shaft:T apered Key shaft}PV E19/21S AE“A”T hru-drivesThru-DIM.“A”DIM.“B”DIM.“C”MaxT orque Rating Couplingshaft Spline Data mm(in.)mm(in.)mm(in.)N.m(In.lbs.)Length Dim“D”mm(in.)

Essential information on the correct methods for treating hydraulic fluid is includedin Danfoss publication561“Danfoss Guide to Systemic Contamina tion Control”available from your local Danfoss distributor or by contacting Danfoss Hydraulics. Recommendations on filtration and the selectionof products to control fluid condition are included in561.Recommended cleanlinesslevels,using petroleum oilunder common conditions,are based on the highestfluid pressure levels in thesystem and are coded inthe chart below.Fluidsother than petroleum,severe service cycles,ortemperature extremes arecause for adjustment ofthese cleanliness codes.See Danfoss publication561for exact details.Danfoss products,as anycomponents,will operatewith apparent satisfactionin fluids with highercleanliness codes thanthose described.Othermanufacturers will oftenrecommend levels abovethose specified.Experiencehas shown,however,that life of any hydrauliccomponent is shortenedin fluids with highercleanliness codes thanthose listed below.Thesecodes have been proven toprovide a long,trouble-freeservice life for the productsshown,regardless of themanufacturer.Fire resistant fluidsWater glycol,phosphateester and polyol ester fluidsmay be used with PVEpumps.With the PVE012and PVE19,systempressure and input speedshould not exceed140bar(2000psi)and1800r/min.System temperatureshould not exceed54°C(130°F).Inlet vacuumshould not exceed101,6millibar(3in.Hg.).Hydraulic fluids andtemperature rangesUse antiwear hydraulicoil,or automotive typecrankcase oil designationsSC,SD,SE or SF per SAEJ183FEB80.Select a viscosity gradethat will allow optimumviscosity,between40cSt(180SUS)and16cST(80SUS),to be achieved withinthe optimum performanceenvelope shown.For further information,seeDanfoss Hydraulic Hints andTrouble Shooting Guide.Ordering procedureOrder PVE pumps by thefull model designation.Pump displacement,mounting flange type,direction of rotation,pumpconfiguration,shaft endtype,seals,pressureadjustment range,specificcontrol functions are allspecified in the full modelcode.28Notes29Danfoss Power Solutions is a global manufacturer and supplier of high-quality hydraulic and electric components.We specialize in providing state-of-the-art technology and solutions marine sector.Building on our extensive applications expertise,we work closely with you to ensure exceptional performance for a broad range of applications.We help you and other customers around the world speed up system development,reduce costs and bring vehicles and vessels to market faster.Danfoss Power Solutions –your strongest partner in mobile hydraulics and mobile Go to for further product information.outstanding performance.And with an extensive network of Global Service Partners,we also provide you with comprehensive global service for all of our components.Local address:DanfossPower Solutions GmbH &Co.OHG Krokamp 35D-24539Neumünster,Germany Phone:+4943218710DanfossPower Solutions ApS Nordborgvej 81DK-6430Nordborg,Denmark Phone:+4574882222DanfossPower Solutions (US)Company 2800East 13th Street Ames,IA 50010,USA Phone:+15152396000DanfossPower Solutions Trading (Shanghai)Co.,Ltd.Building #22,No.1000Jin Hai Rd Jin Qiao,Pudong New District Shanghai,China 201206Phone:+862120806201Danfoss can acceptno responsibility for possible errors in catalogues,brochures and other printed material.Danfoss reserves the right to alter its products without notice.This also applies to productsagreed.All trademarks in this material are property of the respective companies.Danfoss and the Danfoss logotype are trademarks of Danfoss A/S.All rights reserved.©Danfoss |September 2022•Cartridge valves •DCV directional control valves•Electric converters •Electric machines •Electric motors •Gear motors •Gear pumps •Hydraulic integrated circuits (HICs)•Hydrostatic motors •Hydrostatic pumps •Orbital motors •PLUS+1®controllers •PLUS+1®displays •PLUS+1®joysticks and pedals•PLUS+1®operator interfaces•PLUS+1®sensors •PLUS+1®software •PLUS+1®software services,support and training •Position controls and sensors•PVG proportional valves •Steering components and systems •TelematicsHydro-Gear Daikin-Sauer-Danfoss。
