Proportional 2-Wege-Stromregelpatrone(Steckspule, integrierte Elektronik) QNPPM33_ME

Proportional throttle valves, proportional flow control valves M33x2

Direct operated, pressure compensated proportional flow control valve as screw-in cartridge for cavity according to ISO 7789. With the solenoid deenergised, the control spool is held in the closed position by a spring. 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). The control takes place via an analogue interface or a fieldbus interface (CANopen, J1939 or Profibus DP). The parameterisation takes place by means of the free of cost parameterisation and dia­gnostics software «PASO» or via fieldbus interface. For the control, Wandfluh proportional amplifiers are available (see register 1.13).

Proportional 2-way flow control cartridge with integrated electronics​

  • direct operated
  • Qmax = 63 l/min
  • QN max = 63 l/min
  • pmax = 350 bar


Proportional flow control valves with integrated electronics are perfectly suitable for demanding applications in which the volume flow frequently has to be changed. They are used in applications where high valve-to-valve reproducibility, easy installation, comfortable operation and high precision are very important. The integrated controller reliefs the machine control and operates the volume flow control in a closed loop circuit. 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.
