Pressure compensator cartridge U_FPM22

Flow control valves, pressure compensation valves , fine feed / fast approach units M22x1,5

Pressure compensator valve with fixed setting in screw-in cartridge construction for cavity according to ISO 7789. The task of the pressure compensator is to keep the pressure drop via a throttle point (e.g. control edge of a spool valve) almost constant. It ensures that a determined amount of oil, independent of the load pressure, flows through the spool valve when the control spool is in a specific position. Pressure compensating valves are mostly used in conjunction with proportional valves. ​ ​ ​ ​

  • 2- and 3-way function
  • Qmax = 25 l/min
  • pmax = 350 bar


2-way pressure compensation valve: Volume flow changes due to pressure or load changes at the consumer are corrected. Cylinder or motor speeds remain constant. If several consumers are operating in parallel, the full system pressure is available to each one. 3-way pressure compensator valve: Excess pump flow rate is fed to the return system. Especially in the mobile area, where the necessary cooling surfaces are missing, this prevents the hydraulic ­system from overheating. Parallel operation is not possible. If there are several consumers, the pump pressure is adapted to the ­highest working pressure. 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. ​
