High-Sensitivity Big Flow Steam Pressure Reducing Valve

YI CHENGas Pressure Reducing ValveStructural characteristic and purpose
his series reducing valve is pilot piston type reducing valve, mainly composed of main valve and pilot valve. The main valve consists f valve seat, main valve disc, piston, cylinder sleeve, and spring. The piston valve consists of valve seat, valve flap, membrane, spring nd adjusting spring.
he product made big improvement on the basis of normal pressure reducing valve, enlarge the piston area, change the throttle tructure, change the sealing manner, improve the pilot structure and manner of adjusting spring, thus to improve the performance of he product in aspects of sensitivity, flow, and service life.
he product is mainly applied on steam piping, to reduce and regulate the pressure.Name of componentMaterial of componentValve body, valve cover, seat coverWCBValve seat, valve flap2Cr13Cylinder sleeve, PistonAmpcoMembrane1Cr19Ni9TiPiston ringAlloy cast iron/ polyphenylPilot valve seat, pilot valve rod2Cr13Spring of main valve50CrVAMain spring of pilot valve50CrVAAdjusting valve60Si2Mnmain technical parameters and indexes of performance Ÿ
