Qinghai gas pressure reducing valve gas pressure reducing valve hydrogen pressure reducing valve YK42X, YK43F

The gas pressure reducing valve is a pilot piston pressure reducing valve. It consists of two parts, the main valve and the 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, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting and adjusting the spring pressure, the outlet pressure changes are sensed by the diaphragm, and the size of the over-flow area of the main valve throttling part is adjusted by the pilot valve opening and closing to drive the piston to realize the function of pressure reduction and pressure stabilization. The gas pressure reducing valve is mainly used for gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
