YK43X/F Type Pilot Operated Gas Pressure Reducing Valve

Product Details

YK43X/F Type Pilot Operated Gas Pressure Reducing Valve
Structure Characteristic And Purpose.

This series pressure reducing valve is pilot piston type pressure reducing valve,mainly composed of main valve and pilot valve.The main valve consists of valve seat,main valve disc,piston,cylinder liner 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.
