| Message: | 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, cylinder sleeve, and spring. The piston valve consists of valve seat, valve flap, membrane, spring and adjusting spring. Set the outlet pressure through adjusting spring, sense the change of pressure of outlet with membrane, adjust the flow area of throttling part of main valve through open and close of pilot valve and drive the piston, to realize the function of reducing and regulating valve. The product is mainly applied on steam piping, to reduce and regulate the pressure.
