Soupape de réduction de pression autopilotée, série R4R/R4R*P2

As versatile pilot operated pressure reducing valves for subplate 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...
