YK43X / F gas pressure reducing valve is mainly used for gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.

share to:

First, YK43X / F gas pressure reducing valve structural features and uses:

This series of 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. 力变化,通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小,实现减压稳压功能。 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.
This product is mainly used for gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
