High-flow, Pressure Compensated Proportional Valve

The P447 is a high-flow, pressure compensated proportional valve.

It enables the design of compact low-power instruments, mixing and dosing gases, and regulating pressure.

This valve is ideal for downstream pressure and flow regulation. Its pressure compensation mechanism allows for:

  • pressure range of -1 to 7 bars and
  • flow rate of 170l/min @3 bar in a miniature footprint


  • Downstream pressure regulation
  • Flow control
  • Venturi flow control
  • Pilot pressure regulator
  • Air motor
  • Mass Flow Controller (MFC) Read more.
