Product Description
Y42X Stainless Steel Flanged Pressure Reducing Valve This series of pressure reducing valves is a direct-acting thin-film spring pressure reducing valve. It is mainly composed of adjusting spring, diaphragm, piston, valve seat, valve clack and other parts. The diaphragm is used to directly sense the downstream pressure to drive the valve flap, and control the opening of the valve flap to complete the function of pressure reduction and stabilization. In the cold and hot water supply system of urban buildings and high-rise buildings, it can replace conventional partitioned water pipes and save equipment. It can also be used for pressure reduction and stabilization in the usual cold and hot water pipe network. This product has smooth pressure regulating and stabilizing action, and is suitable for pipelines of water and non-corrosive liquid media.
