Y42X Y42F Water pressure reducing valve

Y42X Y42F Water pressure reducing valve Product introduction

　Y42X Y42F Water pressure reducing valve is direct acting diaphragm spring structure, Y42X Y42F Water 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 water pressure reducing valve opening can be controlled to realize pressure reduction and pressure stabilization. Y42X Y42F Water 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 Y42F Water pressure reducing valve can also be in the usual hot and cold pipeline.
