Pressure relief cartridge, stainless BV_PM22_K9

Pressure relief, backpressure, pressure sequence, accumulator unloading valves M22x1,5

Pilot operated pressure relief valve in screw-in cartridge construction for cavity according to ISO 7789. High flow capacity, very sensitively adjustable. If the pressure in P (1) exceeds the adjusted value of the valve, the excessive pressure is drained to T (2). Rapid switching with low hysteresis and excellent stability over the whole flow range. The small clearance of the hardened spool ensures a low leakage volume flow. The stainless execution is especially suitable for the use in wet and salty environment. ​ ​

These valves are used for limiting the operating pressure in the hydraulic system or for protection against pressure peaks. Can be used in double pressure relief switches. For machining the cart­ridge cavity in steel and aluminum blocks, cavity tools are available (hire or purchase). Please refer to the data sheets in register 2.13.
