Полное описание продукта

Parker's versatile pilot operated pressure reducing valves series R5R with manual adjustment and series R5R*P2 with proportional solenoid adjustment provide high flow and ensure a constant pressure in the secondary part of the hydraulic system. They are part of the Parker valve range with SAE flanges which is unique in its variety.

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. The SAE flanges allow to mount the valves directly on the inlet flanges of actuators to achieve a very compact design.

Series R5R*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.
