Two-stage pressure reducing valves are used for low-pressure output, Where pressure precision and outlet flow requirements are high, Can be used with various gas cylinders and gas pipelines, The valve body reduces pressure in 2 stages, Outlet pressure is more stable than that of ordinary single-stage reducing valves.
