YK43X pilot piston gas pressure regulator introduced

This series of pilot-piston gas pressure reducing valve belongs to the pilot piston type pressure reducing valve. The main valve and pilot valve composed of two parts. The main valve from the valve seat, the main valve disk, piston, spring and other components. Pilot valve mainly by the valve seat, disc, diaphragm, spring, adjusting spring and other components. By adjusting the spring pressure to set the outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttle flow area, to achieve decompression regulator function. The pilot-style large diaphragm high sensitivity pressure reducing valve is mainly used for gas lines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
