Product details

YK43 type gas pressure reducing valveIt belongs to the pilot piston pressure reducing valve. It consists of two parts: the main valve and the pilot valve. The main valve of YK43 gas pressure reducing valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The YK43 gas pressure reducing valve pilot valve is mainly composed of components such as valve seat, valve disc, diaphragm, spring, and regulating spring. By adjusting the spring pressure to set the outlet pressure, using a diaphragm to sense changes in outlet pressure, and driving the piston to adjust the size of the overcurrent area at the throttle position of the main valve through the opening and closing of the pilot valve, the pressure reduction and stabilization function is achieved.
YK43X gas pressure reducing valve is mainly used in gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
