YK43X/F stainless steel hydrogen Pressure relief valve Details of:
Product features: The pilot piston type gas pressure reducing valve belongs to the pilot piston type pressure reducing valve. It consists 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, regulating spring and other parts. Set the outlet pressure by adjusting the pressure of the regulating spring, use the diaphragm to sense the change of the outlet pressure, and adjust the size of the overflow area of the throttling part of the main valve by opening and closing the pilot valve to achieve the function of reducing and stabilizing pressure. The pilot 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.
