YK42F Stainless steel pressure reducing valve is designed on base of Y42X diaphragm pressure reducing valve,there are two pressure gauge on the valve body or flange to check inlet and outlet pressure, YK42F Pressure reducing valve is direct acting diaphragm spring structure,the 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 YK42F Pressure reducing valve opening can be controlled to realize pressure reduction and pressure stabilization.YK42X 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.YK42F Pressure reducing valve can also be in the usual hot and cold pipeline. 
 
YK42X Pressure reducing valve is suitable for pipelines of water and non-corrosive liquid media.
