Yk43f/h piston type gas pressure reducing valve

Overview of piston gas pressure reducing valve

This series of gas pressure reducing valves are pilot piston pressure reducing valves. It is composed of main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. The gas pressure reducing valve sets the outlet pressure by adjusting the spring pressure, uses the diaphragm to sense the change of outlet pressure, and uses the pilot valve to open and close the driving piston to adjust the size of the overflow area at the throttling part of the main valve, so as to realize the function of pressure reduction and stabilization. Piston type gas pressure reducing valve is mainly used for gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
