Spring diaphragm pressure reducing valve
It is a direct acting diaphragm spring pressure reducing valve. Spring diaphragm pressure reducing valve is mainly composed of adjusting spring, diaphragm, piston, valve seat, valve disc and other parts. The diaphragm is used to directly sense the downstream pressure to drive the valve disc and control the valve disc opening to complete the pressure reducing and stabilizing function.
Spring diaphragm pressure reducing valves can replace conventional partitioned water pipe saving equipment in hot and cold water supply systems of urban buildings and high-rise buildings. It can also play a role in reducing and stabilizing pressure in common hot and cold water pipe networks.
The direct-acting diaphragm spring pressure reducing valve has smooth pressure regulation and stabilizing action and is suitable for pipelines with water and non-corrosive liquid media.
