FLeX SeriesTECHNICAL FEATURESSRVC*2-STAGE, SOLENOID-OPERATEDADJUSTABLE RELIEF VALVESERIES 1, CAVITY: T-10ASolenoid-operated, 2-stage, adjustable balanced pistonrelief cartridges are pressure regulating valves. Energizingthe solenoid activates or deactivates the relief function.Four versions are available.RVCK-LJ*4PORT2PORT135Non-removableAdjust ScrewMain Chamber6RVCK-LJ*Function: The RVCK is normally vented. The pressure dropfrom port 1 (supply, pump) to port 2 (tank) is typically100 psi (see performance curves). When the solenoidis energized, the tube (4) moves and blocks the directconnection between main chamber (3) and tank (port 2).Pilot flow can no longer flow to tank directly. The valve isin relief mode. The pressure setting is adjustable (5).Pilot CN-LJ*PORT2PORT136RVCL-LJ*Function: The RVCL is normally in relief mode. Thepressure setting is adjustable (5). When the solenoid isenergized, the tube moves and opens a direct connectionbetween main chamber (3) and tank (port 2). The valve isnow vented. Pressure drop from port 1 (supply, pump) toport 2 (tank) is typically 100 psi (see performance curves).RVCM-LJ*Function: The RVCM is normally in relief mode. Thepressure setting is adjustable (5). When the solenoid isenergized, the tube (4) moves and blocks the connectionbetween main chamber (3) and pilot stage (6). Withoutpilot flow, the main chamber is closed. The valve blocksthe flow path from port 1 to port 2 like a spool-typedirectional valve.RVCN-LJ*Function: The RVCN is normally blocked. De-energized,the valve blocks the flow path from port 1 to port 2 likea spool-type directional valve. When the solenoid isenergized, the tube (4) moves and allows flow throughthe main chamber (3) to the pilot stage (6). The valve is inrelief mode. The pressure setting is adjustable (5).TECHNICAL FEATURESAll FLeX Series valves incorporate the Sun floating-style construction.Designed and tested to 10-million operational cycles at full rated pressure.Exceeds the new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.A 150-micron stainless steel screen protects the main stage orifice of all valves.Zinc-nickel plating standard for 1000-hour salt fog protection.All RVC* valves are adjustable under pressure, featuring a leak-free adjustment screw with a mechanical stopto prevent the screw from backing out.All valves in the RVC* family use the high-power (25-W) and hazardous location coils. See table on page 3 .Coil connector options offer ratings up to IP69K. See individual coil product pages for details.Includes high flow rates of 25 gpm (100 L/min).FLeX Series solenoid valves are compatible with the XMD Mobile Drivers from Sun.U.S. Patent Numbers: RVCK 10,533,584; RVCL 10,557,483; RVCM 10, 570,932; RVCN 10,774,8532 2021 Sun Hydraulicswww.sunhydraulics.com

APPLICATIONSFLeX SeriesSYSTEM1RVCK-LJ*PUMP START-UP CIRCUITThe normally open ventable relief RVCK is the ideal valve to usein a system when starting up a prime mover connected to a largepump with load. Unloading the pump is good practice and will beless stressful on the system. Since these valves can be switched atpressure, once the prime mover is up to full speed, the relief valvecan be energized to build up system pressure. The pressure is useradjustable up to 5000 psi.2MSYSTEMRVCL-LJ*1PUMP START-UP FOR ON/OFF FAN DRIVE CONTROLThe ventable relief RVCL is normally in relief mode. It is another optionfor pump start-up. Unlike the normally open RVCK, the RVCL is in reliefmode when de-energized for more energy savings during normalsystem operation.2Because the RVCL is in relief mode when de-energized, it is onlynecessary to power the solenoid when the valve needs to unloadduring prime mover start up.MThis makes the valve an obvious choice for a simple hydraulic on-offfan drive circuit as shown here and is a better choice when safetyrequires system pressure in the event of electric power loss.RVCM-LJ*CONVEYOR BELT MOTOR CONTROLThe blockable relief RVCM is normally in relief mode. When energizedthe valve blocks flow like a spool type 2-position, 2-way valve. Thevalve is ideal for circuits that require two pressure setting.In the example of a conveyor belt, the high inertia load requires a highpressure to accelerate from stop. When the conveyor is in motion andmotor speed is constant, a lower relief setting maintains motion at alower pressure.121000 psiCompared to a circuit with two relief valves and one solenoidoperated directional valve, the blockable RVCM eliminates the needfor the directional valve, creating a much simpler two-valve solutioninstead of three.5000 psiNOTE: Sample circuits are shown for application illustration onlyand are not intended as circuit designs.6 2021 Sun Hydraulicswww.sunhydraulics.com

FLeX SeriesAPPLICATIONSRVCM-LJ*BI-DIRECTIONAL PUMP PRESSURE DIFFERENTIAL LIMITThe blockable relief RVCM is normally in relief mode. The valvecan be used to limit the pressure differential across the motor.The relief valve setting then allows the motor to accelerate with alimited torque using the controlled pressure, smoothing out theload movement.12In a rectifier circuit, the RVCM limits the torque of the motor inboth directions.243Coil A1Coil BP TRVCN-LJ*ADJUSTABLE COMPRESSION FOR MATERIAL COMPACTORS& BAILING PRESSESThe RVCN is normally blocked and, when energized, turns into anadjustable relief valve.1The valve can be used as a pilot-operated 2-position, 2-way valvewith high capacity. When energized, the relief function of thevalve can be used to avoid decompression shock. In a continuousregeneration circuit, the valve can unload the rod end side of thecylinder. Preloading the cylinder avoids the decompression shock.And because the valve is adjustable, it can be adjusted to control theamount of compression in the compactor or press when the cylindergoes from regen to normal mode.2Coil A2431Coil BP TNOTE: Sample circuits are shown for application illustration onlyand are not intended as circuit designs.www.sunhydraulics.com 2021 Sun Hydraulics7
