Proportional 2-way flow control cartridge QNPPU16

Proportional throttle valves, proportional flow control valves 1- 5/16"-12UN

Direct operated, load compensated proportional flow control valve as screw-in cartridge for UNF cavity. 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). For the control, Wandfluh proportional amplifiers are available (see register 1.13). ​

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

Application

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. 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. ​ ​ ​ ​
