YK42X YK42F Pressure reducing valve Product introduction

 YK42X YK42F Pressure reducing valve is direct acting diaphragm spring structure, which is updated on base of Y42X Y42F Pressure reducing valve,both flanges end installed the pressure guage to witness inlet and outlet pressure. YK42X YK42F 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.YK42X YK42F 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.YK42X YK42F Pressure reducing valve can also be in the usual hot and cold pipeline.
