Operation / Usage

  • Ideal for process gas supply where pressure accuracy is required even when inlet pressures and flow rates are varying.
  • High flow rates and outlet pressure accuracy are achieved, even when the difference between inlet and outlet pressures is small.
  • Own-medium controlled, with integrated pilot gas regulator, meaning no separate gas supply is required.


  • Annual testing of body leak tightness is recommended.
  • Depending on application, moving wetted parts may need periodic replacement.
