Product Description

YK43F/H-GVPR08 Pilot Piston Gas Pressure Reducing Valve
Brief Introduction.
This series reducing valve is pilot piston type reducing valve, 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 gas piping, such as air, nitrogen, oxygen, hydrogen, liquefied gas, and natural gas.
