Pilot Operated Pressure Reducing Valve, In-line Mounting - Series R4R / R4R*P2 026-20305-0

Parker in-line mounted pilot operated pressure reducing valves series R4R ensure a constant pressure in the secondary part of the hydraulic system. Series R4R*P2 enables a continuous adjustment by the proportional solenoid operated pilot stage.

As versatile pilot operated pressure reducing valves for in-line mounting, Parker's series R4R with manual adjustment and series R4R*P2 with proportional solenoid adjustment provide high flow and ensure a constant pressure in the secondary part of the hydraulic system. Independent of the primary pressure, the secondary pressure is reduced to the pressure setting. In order to avoid unintended motion of the actuator, the valves are normally closed. For single functions – where no manifold blocks are used – the valves can be directly placed in the pipework.

Series R4R*P2 has additionally a proportional solenoid operated pilot stage and a cartridge main stage. The optimum performance can be achieved in combination with the digital amplifier module PCD00A-400.
