YX741XThe adjustable pressure reducing and stabilizing valve is composed of main valve and needle type regulating valve, pilot valve, ball valve and connecting pipe system. The main valve body adopts full channel, direct current and streamline design, and adopts diaphragm type or piston type structure. This product sets the outlet pressure by setting the spring pressure of the pressure regulating pilot valve and adjusting the opening of the needle valve, and stabilizes the outlet pressure through the feedback function of the connecting pipe system and the control room. The needle type regulating valve and pilot valve are used for water pressure self-control without additional devices and energy sources. The maintenance is simple, the influence of inlet pressure and flow is small, the accuracy of pressure control is high, and the pressure reduction and stabilization are reliable. It is mainly used in high-rise buildings, industrial and mining enterprises, medicine, food and other fields of pipeline system to reduce the higher upstream pressure to meet the requirements of the downstream normal use pressure.
