Proportional throttle cartridge (slip-on coil) D_PPM22

Proportional throttle valves, proportional flow control valves M22x1,5

Direct operated proportional throttle valve in screw-in cartridge construction for cavity according to ISO 7789. With the solenoid deenergised, the control spool is held in the closed position (DN) or open position (DO) by a spring. The change of the electric current is followed by a proportional volume flow change. Very sensitive opening and closing characteristics and low hysteresis are characteristics of these valves. For the control, Wandfluh proportional amplifiers are available (see register 1.13).

Proportional throttle cartridge​

  • direct operated
  • Qmax = 32 l/min
  • QN max = 25 l/min
  • pmax = 350 bar


Proportional throttle valves are suitable for smooth control of movements in stationary or mobile systems. 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.
