Pressure relief, backpressure, pressure sequence, accumulator unloading valves M33x2
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.
Pressure relief cartridge
- pilot operated
- pmax = 400 bar
- pN max = 350 bar
- Qmax = 230 l/min
Application
These valves are used for limiting the operating pressure in the hydraulic system. The screw-in cartridge is perfectly suitable for installation in control blocks. 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. Attention: Not to be used in applications with periodically changing flow direction.
