      YK43X natural gas pressure relief valve is a pilot piston pressure relief valve. It is composed of main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, cylinder liner, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. By adjusting the spring pressure and setting the outlet pressure, the diaphragm is used to sense the change of the outlet pressure, and the piston is driven by the pilot valve to adjust the throttle area of the main valve to realize the function of reducing pressure and stabilizing pressure.

      YK43X natural gas pressure relief valve is mainly used for natural gas pipeline, but also for air, nitrogen, oxygen, hydrogen, liquefied gas and other gases.
