Introduction of YK43F/X High Pressure Gas Decompression Valve
YK43F/X high pressure gas relief valve belongs to pilot piston relief valve. It consists of main valve and pilot valve. The main valve is mainly composed of seat, main disc, piston, spring and other parts. The guide valve is mainly composed of seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the outlet pressure change, and the pilot valve opens and closes to drive the piston to adjust the flow area of the throttle part of the main valve, so as to realize the function of reducing pressure and stabilizing pressure. This product is mainly used in gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
