Proportional 2-way flow control cartridge QZPPM18

Proportional throttle valves, proportional flow control valves M18x1,5

Direct operated, pressure compensated proportional flow control valve in screw-in cartridge construction for cavity according to Wandfluh standard. When the solenoid is deenergised, the control spool closes practically leakage-free. The change of the electric current is followed by a proportional volume flow change. From the input (1), the fluid flows over the control and throttling spool to the controlled output (2). For the control, Wandfluh proportional amplifiers are available (see register 1.13).

Proportional 2-way flow control cartridge​

  • direct operated
  • Qmax = 2 l/min
  • QN max = 2 l/min
  • pmax = 350 bar


Proportional flow control valves are suitable for precise speed ­control, where the load current has to be maintained constant independent of the input and output pressure. 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.
