YK43X Piston gas pressure reducing valve Feature
YK43X piston gas pressure reducing valve belongs to pilot piston type pressure reducing valve.YK43X pilot 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.
.YK43X piston gas pressure reducing valve is mainly used for gas pipeline, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases. -
