Adjustable Pressure Reducing And Stabilizing Valve AX741X-10Q/16Q

The YX741X adjustable pressure reducing and stabilizing valve is a special valve installed on the pipeline of the water supply and drainage system in high-rise buildings, which reduces the inlet pressure to a certain required outlet pressure. The valve relies on its own energy to maintain a stable outlet pressure at the set point, that is, the outlet pressure does not change due to changes in inlet pressure and flow rate. The valve control system is equipped with a self-cleaning filter at the inlet, which utilizes the characteristics of the body to prevent suspended particles with larger density and diameter from entering the control system, ensuring smooth circulation and safe operation of the valve. The system operates smoothly, with high intensity and long service life.

Working principle:
When the pipeline supplies water from the inlet end, the water flows through the needle valve and enters the main valve control room. The outlet pressure is applied to the pilot valve through the pipeline. When the outlet pressure is higher than the set value of the pilot valve, the pilot valve closes and the control room stops draining. At this time, the pressure in the main valve control room increases and the main valve is closed, and the outlet pressure no longer increases. When the outlet pressure drops to the set pressure of the pilot valve, the pilot valve opens and the control room discharges water downstream. Due to the displacement of the pilot valve being greater than the inlet of the needle valve, the pressure in the control room of the main valve decreases, and the inlet pressure causes the main valve to open. In a stable state, the inlet and outlet of the control room remain the same, the opening remains unchanged, and the outlet pressure remains unchanged. Adjust the pilot valve spring to set the outlet pressure.

Product features:
The YX741X adjustable pressure reducing and stabilizing valve consists of a main valve, a needle type regulating valve, a guide valve, a ball valve, and a connecting system. The main valve body adopts a full channel, direct current, and streamlined design, and adopts two types of structures: diaphragm or piston. This product uses a set pressure regulating guide valve spring pressure and an adjustable needle valve opening to set the outlet pressure, and stabilizes the outlet pressure through feedback from the connecting system and control room. The YX741X adjustable pressure reducing and stabilizing valve utilizes needle type regulating valves and pilot valves for water pressure self control, without the need for additional devices and energy sources. It is easy to maintain and is less affected by inlet pressure and flow rate, with high accuracy in pressure control and pressure reducing and stabilizing.

1.Stable pressure control.The pilot valve and main valve work continuously, and the downstream pressure changes continuously and steadily, with little influence from the inlet pressure. 2. The AX742X safety relief/holding valve is easy to operate. After setting the working pressure, the main valve automatically adjusts when the upstream pressure or flow changes, stabilizing the downstream pressure. 3. The valve body adopts a full channel, direct current, and streamlined design. Low hydraulic loss.

Function and purpose:
This valve is generally installed upstream of the water supply network system to achieve the function of reducing pressure and stabilizing pressure on its downstream network or device. This series of valve products is widely used for water pressure control in high-rise buildings, living areas, or other water supply network systems.
