Pressure Regulator 737 LE

Dome pressure regulator 737 LE 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.

Dome pressure regulator 737 LE 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.

Benefits:

  • high pressure stability even when subject to fluctuations in withdrawal enables process reliability;
  • 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;
  • additional connections (G 1/8 F) in the inlet and outlet range – e. g. pressure transmitter;
  • connection for wall mounting panel;
  • easy installation and removal.

Options:

  • control via electrical proportional valve;
  • piloting by foreign gas available;
  • wall mounting panel;
  • filter.
