Designed to reduce the pressure of natural gas from high or medium pressure to the required values, as well as to perform the following functions:
automatic maintenance of the output pressure within the specified limits regardless of changes in flow rate and input gas pressure (within the specified range of their values);automatic shutdown of gas supply when the output pressure rises or falls above or below the permissible specified values; gas purification from mechanical impurities; measurement of volumetric flow rate and gas volume (gas flow metering).Designed to reduce the pressure of natural gas according to GOST 5542 from the input value (up to 1.2 MPa inclusive) and maintain it within the specified limits. Types of climatic execution U1 according to GOST 15150 (but with ambient air temperature from minus 40 to plus 45º?) and UHL1 with ambient air temperature from minus 60 to plus 40º?
(for the air temperature of the coldest five-day period)..
