Pilot operated self-actuated pressure reducing valve

The self‑operated pressure reducing valve automatically reduces the inlet pressure to a desired outlet pressure, utilizing the energy of the medium itself to help maintain stable outlet pressure. While the valve introduces some pressure loss, it can help reduce medium waste and optimize system flow distribution, contributing to improved system arrangement and operating conditions. For steam service, pilot‑operated piston or diaphragm pressure reducing valves are generally recommended. To facilitate operation, adjustment, and maintenance, the valve should typically be installed in horizontal piping.
