Product details
Piston type pressure reducing and stabilizing valve Y42X

Y42XSpring diaphragm reducing valveIt belongs to the direct acting thin film spring pressure reducing valve. The Y42X spring diaphragm pressure reducing valve is mainly composed of regulating spring, diaphragm, piston, valve seat, valve disc and other parts. By using a diaphragm to directly sense downstream pressure and drive the valve disc, the opening of the valve disc is controlled to achieve the function of pressure reduction and stabilization.
The Y42X spring film pressure reducing valve can replace conventional partitioned water pipes and save equipment in the cold and hot water supply systems of urban and high-rise buildings. It can also play a role in reducing pressure and stabilizing pressure in typical hot and cold water pipe networks.
Y42X direct acting thin film spring pressure reducing valve has smooth pressure regulation and stabilization action, suitable for pipelines with water and non corrosive liquid media.
