Product Description

YK43F hydrogen pressure reducing valve Structure features and uses YK43F hydrogen pressure reducing valve is a pilot piston type pressure reducing valve. It is composed of two parts: the main valve and the pilot valve. The main valve is mainly composed of the seat, the main valve disc, the piston, the spring and other parts. Set the outlet pressure by adjusting the spring pressure, use the diaphragm to sense the outlet pressure change, and drive the piston to adjust the size of the flow area of the main valve throttling part through the pilot valve, so as to achieve the function of reducing pressure and regulating pressure. YK43F hydrogen pressure reducing valve is mainly used for gas pipelines, such as gas, nitrogen, oxygen, hydrogen, natural gas, liquefied gas and other gases.
