Description：YK43X/F Air gas pressure reducing valve manufacturer, factory and supplier.

YK43X/F Air gas pressure reducing valve manufacturer, factory and supplier. YK43X/F Air gas pressure reducing valve belongs to pilot piston type pressure reducing valve. YK43X/F Air gas pressure reducing valve is mainly used for gas pipeline, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases. YK43X/F Air gas pressure reducing valve is composed of main valve and pilot valve.Main valve consists of seat, disc, piston, spring and other components.The guide valve mainly consists of seat, disc, diaphragm, spring, adjusting spring and other parts.The outlet pressure is set by adjusting the spring ,which is transfer the outlet pressure changes according to the diaphragm sensor, and the piston is driven through the opening and closing of the guide valve to adjust the flow area of the main valve throttling position, so as to realize the pressure reducing and pressure stabilizing function.

K43X YK43F Gas pressure reducing valve installation instruction

1. In order to facilitate operation and maintenance, the gas pressure reducing valve is generally installed vertically on the horizontal pipeline, and the horizontal installation must be specified.

2. During installation, attention should be paid to the flow direction of the intermediate material of the pipeline and the direction of the arrow shown on the gas reducing valve.

3. In order to prevent overpressure after the gas pressure reducing valve, a safety valve should be installed at not less than 4M from the valve outlet.
