Pressure reducing valves are commonly used in water distribution systems, gas pipelines, and steam systems to protect downstream equipment and processes from damage due to excessive pressure. They are also used in fire protection systems, heating and cooling systems, and pneumatic systems to regulate pressure and ensure the proper operation of these systems.. Pilot-operated valves use a pilot control system to regulate the pressure, while direct-acting valves use a diaphragm or piston to control the opening of the valve

صمام تخفيض الضغط. Balanced valves use a combination of forces to maintain a constant pressure downstream.
