Gas regulating installations (GRU)

Gas through shut-off valves (ball valves) enters the gas filter, where it is cleaned of mechanical impurities. The gas filter is equipped with a differential pressure indicator to determine the degree of clogging of the filter elements. After cleaning, the gas enters the pressure regulator unit, in the regulation unit it decreases and the gas pressure is maintained within the specified limits at the outlet. The gas pressure regulator unit is an RDNK-400 gas pressure regulator (or another, depending on the customer's requirements) with a built-in safety shut-off valve. From the regulator through the valve, gas flows to the consumer. Gas control units GRU constructively allow disconnecting the filtration and reduction line for preventive maintenance work with a filter and a regulator, both in the main line and in the reserve one. GRUs are completed with equipment depending on the needs of the customer.
