Y13H / Y female piston steam pressure reducing valve material:WCB, stainless steel female connection medium:steam

Y13H / Y female piston steam pressure reducing valve Y13H / Y female piston steam valve Product Description Structural features and usefulness This series belongs to the pilot valve piston valve. From the main valve and pilot valve two parts. Mainly by the main valve seat, the main valve plate, piston, cylinder liner, springs and other parts. Mainly by the pilot valve seat, valve, diaphragm, spring, adjusting springs and other parts. By adjusting the outlet pressure adjusting spring pressure setting, the use of outlet pressure sensing diaphragm, the drive piston through the guide opening and closing the valve adjust the main throttle valve flow area size of the parts to achieve the pressureregulator function. Female piston steam valve is mainly used for steam piping, from the vacuum regulator role. main specification and technial parameter
