      • Ordering Process

      The Y42X spring membrane pressure reducing valve belongs to the direct acting membrane spring pressure reducing valve. Y42X spring film pressure relief valve is mainly composed of regulating spring, diaphragm, piston, valve seat, disc and other parts. The diaphragm is used to directly sense the downstream pressure to drive the disc and control the disc opening to complete the decompression and voltage stabilizing function.


      Y42X spring membrane pressure relief valve can replace the conventional partitioned water pipe and save equipment in the cold and hot water supply system of urban buildings and high-rise buildings. It can also play a role of reducing pressure and stabilizing pressure in the common cold and hot water pipe network.


      Y42X direct acting membrane spring pressure reducing valve regulates pressure and regulates pressure smoothly. It is suitable for water and non-corrosive liquid pipelines.
