Direct acting spring diaphragm pressure reducing valve
Pressure reduced valve pilot piston steam pressure reducing valve, flange connection form, the structure of the piston, valve seat sealing surface material for Cr13 stainless steel, nominal pressure PN40 ~ PN63, for WCB steam pressure reducing valve body material.
Pressure reduced valve type pilot piston steam pressure reducing valve consists of two parts, the main valve and pilot valve. The main valve is mainly composed of valve seat, the main valve, piston, spring and other parts. Pilot valve is mainly composed of the seat, disc, diaphragm, spring, adjusting spring and other parts. This product made great improvement on the basis of ordinary pressure reducing valve, increased the piston area, changed the throttling and sealing structure, increasing the flow area and so on, to improve the sensitivity, flow, life has been greatly improved in aspects of performance. Is mainly used in steam piping, suitable for high traffic flow change is big, the change of inlet pressure steam piping.
