High-performance dome-loaded pressure regulator-set.
For high and varying flows requiring maximum pressure stability.
A complete solution, applicable as a manifold pressure regulator per DIN EN ISO 7291.

Features

  • Pilot Control Tube (PCT)
    One of the features enabling highly accurate control of outlet pressure
  • Balanced Seat Design (BSD)
    Further enabling control precision, high reliability and low maintenance
  • A complete solution, ready to use
    With integrated pilot pressure regulator, and stainless steel pressure gauges, completely assembled and tested
  • Own-medium controlled
    Enabling autonomous operation
  • Closed system
    No gas is released to atmosphere
  • Simple to install and operate
    Removable spindle enables simple setting of the required outlet pressure. Can be positioned at any angle / orientation. For indoor and outdoor installation.

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.

Maintenance

  • Annual testing of body leak tightness is recommended.
  • Depending on application, moving wetted parts may need periodic replacement.
  • Device-specific Maintenance-Kit available upon request.
