Product Description
Y42X Pressure Reducing Valve (PRV)
Y42X Pressure Reducing Valve
Structural Feature and Function
Y42X type direct effect spring diaphragm reducing valve consists mainly of regulating spring, diaphragm, piston, seat and disc parts etc. Using the diaphragm direct sensing downstream pressure drive disc, control valve disc opening to realize pressure-reducing-and-maintaining function. This product in the urban construction, heat supply system of high-rise buildings, can replace conventional division conduit, saving equipments. It also can usually be in the hot and cold water pipe net, realize pressure reducing-and-stabilizing. This product pressure regulator, smooth movement, suitable for water and the noncorrosive liquid medium pipeline.
