Pilot Operated Steam Pressure Reducing Valve

Y43H Pilot piston type steam pressure reducing valve.
Structural characteristic and purpose
This series reducing valve is pilot piston type reducing valve for steam, mainly composed of main valve and pilot valve. The main valve consists of valve seat, main valve disc, piston, cylinde r sleeve, and spring. The piston valve consists of valve seat, valve flap, membrane, spring and adju sting spring. Set the outlet pressure through adjusting spring, sense the change of pressure of outl et with membrane, adjust the flow area of throttling part of main valve through open and close of pi lot valve and drive the piston, to realize the function of reducing and regulating valve. The produc t is mainly applied on steam piping, to reduce and regulate the pressure.
