Non-return valve hydraulically pilot operated RNXPM22

Non-return valves, pilot operated non return valves, shuttle valves, pipe failure valves, drain valves, 3-way shifting valves M22x1,5

Hydraulically pilot operated non-return valve in screw-in cartridge construction for cavity according to ISO 7789. In the free flow direction (2 → 1), the volume flow opens the spring loaded seat cone. In the opposite direction (1 → 2), the spring keeps the valve closed. If pressure is built up in connection x, the pilot control spool is shifted and the non-return valve of the closed off port is opened by this. The required pilot control pressure depends on the pilot ratio. ​
