Y42X pressure regulating valve is a pressure regulating valve with piston instead of diaphragm.More than three times longer life than the diaphragm type.For diameters less than DN50, it is recommended to use Y110 and Y116 (threaded connection) diaphragm pressure valves;For diametral dry equal to DN50, it is recommended to use Y42X(flange connection) piston type pressure reducing valve.This kind of valve belongs to adjustable pressure reducing valve, the pressure behind the valve can be adjusted according to the need, after putting into use the valve after the pressure is always reduced and stable in the set value, the pressure before the valve, flow fluctuation and change.Valve material selection, reliable performance, long service life.
Y42X Pressure relief valve is mainly composed of adjusting spring, diaphragm, piston, valve seat, valve disc and other parts. The diaphragm is used to directly sense the downstream pressure to drive the valve disc and control the opening of the valve disc to complete the function of pressure reduction and pressure stabilization. This product can replace the conventional partition water pipe and save equipment in the cold and hot water supply system of urban buildings and high-rise buildings. It can also reduce pressure and stabilize pressure in common cold and hot water pipe network. This product can adjust and stabilize the pressure smoothly, and is suitable for the pipeline of water and non corrosive liquid medium.
