Y42X type spring piston water pressure reducing valveDetailed product description：

Y42X pressure reducing valve has smooth pressure regulation and stabilization action, suitable for pipelines with water and non corrosive liquid media. Y42X 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. Y42X 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.
