Y42X Diaphragm pressure reducing valve Feature
Y42X Diaphragm pressure reducing valve is direct acting diaphragm spring structure,Y42X Diaphragm pressure reducing valve mainly consists of adjusting spring, diaphragm, piston, seat, disc and other parts.The pressure downstream of the diaphragm can be directly sensed to drive the disc, and the Y42X Diaphragm pressure reducing valve opening can be controlled to realize pressure reduction and pressure stabilization.Y42X Diaphragm pressure reducing valve can replace the conventional sectional water pipe and save equipment in the cold and hot water supply system of urban buildings and high-rise buildings.Y42X Diaphragm pressure reducing valve can also be in the usual hot and cold pipeline.
Y42X Diaphragm pressure reducing valve is suitable for pipelines of water and non-corrosive liquid media. -
