Pilot piston gas pressure reducing valve

Short Description:

Y43x / F pilot piston pressure reducing valve consists of main valve and pilot valve. The outlet pressure is set by adjusting the spring pressure. The diaphragm is used to sense the change of outlet pressure. The piston is driven by the pilot valve to adjust the flow area of the law enforcement throttling part, so as to realize the function of pressure reduction and pressure stabilization. This product is mainly used for gas pipeline, such as air, nitrogen, liquefied gas, natural gas, etc.
