2-way flow control cartridge QZ_PM33

Flow control valves, pressure compensation valves , fine feed / fast approach units M33x2

2-way flow control valve in screw-in cartridge construction for cavity according to ISO 7789. The valve serves to maintain the speed of a consumer constant independent of the load. The adjustable throttle spool determines the volume flow. When the pressure changes, the pressure compensating piston shifts and changes the flow cross-section so that the pressure difference at the throttle spool is kept constant. ​ ​ ​ ​

  • Qmax = 80 l/min
  • QN max = 70 l/min
  • pmax = 350 bar


In all hydraulic systems in which the volume flow must be kept constant in one flow direction when the load fluctuates. The screw-in cartridge is perfectly suitable for installation in control blocks and is installed in sandwich- (vertical stacked systems) and in flange plates (corresponding data sheets in this register). 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. ​ ​ ​ ​
