Dome pressure regulators 757 LE are designed for gas pipelines and other gas supply systems. Constant operating pressure, irrespective of fluctuations in the volume of gas offtake, ensures stable gas concentration and reliability of the production process. Apart from that, the use of dome-loaded pressure regulators is recommended for systems with high gas flow rate at minor pressure difference.
The dome pressure regulator 757 LE works in conjunction with a pilot pressure regulator (or proportional pressure control valve), through which the required operating (outlet) pressure is adjusted. Both regulated (working) gas and extraneous gas can be used to feed the pilot pressure regulator.
