Industrial gas pressure regulating equipment is a pressure reducing device used to adjust the gas supply pressure in the gas transmission and distribution system. Its basic task is to adjust the higher inlet pressure of the previous stage to the pressure required by the downstream. It is in the gas transmission and distribution pipeline network. It is an important link connecting the various processes. The equipment that composes the pressure regulating station includes valves, safety shut-off valves, safety relief valves, filters, compensators, pressure regulators, measuring instruments, bypass pipes, etc. Because of its compact structure, small floor space, investment saving, and convenient installation and use, it has been widely promoted and applied.
