Powerful and low-maintenance Dome Pressure Regulator applicable for mounting in pipeworks.


  • high pressure stability even when subject to fluctuations in withdrawal enables process reliability
  • Pilot Control Tube (PCT) for particularly high constant outlet pressure
  • applicable for almost all gases
  • accurate dynamic regulation
  • high flow rate
  • Balanced Seat Design (BSD) for better control precision
  • complete mounted, inclusive pressure gauge, pilot pressure regulator and fittings
  • working pressure changable at any given moment  (readjustable) – e.g. due to temperature fluctuations
  • provides constant working pressure by dynamic control
  • no disperse of pilot gas to the environment – closed system
  • pressure gauges optionally in stainless steel and/or filled with glycerine
  • indoor and outdoor installation
  • connection for wall mounting panel
  • easy installation and removing
  • inlet-/outlet fitting with flange DN 80 or DN 100, PN 16/40, DIN 2656 with O-ring 88.5x3 mm


  • control via electrical proportional valve
  • piloting by foreign gas available
  • filter

Operation / Usage:

  • Dome pressure regulator are especially suitable for process supply in pipe-works and system engineering.
  • Independent of withdrawal fluctuations the stability working pressure guarantees a constant gas concentration and quality of the down stream processes.
  • Additionally the use in case of high flow rates at low pressure drops is recommended.


  • The dome pressure regulator is used in combination with pilot pressure regulator (or proportional valve) for adjusting the required working pressure (outlet pressure).
  • It’s possible to use the regulated gas (own medium) or foreign gas as supply of pilot pressure regulator by option.


  • Annual testing of body leak tightness is recommended.
  • Replace wearing parts at least every 1-3 years.
  • Premounted Maintenance-Kit on request.

Company certified to ISO 9001, ISO 22000 and PED 97/23/EC Module H
