  • Product Introduction
  • Service Promise
  • Ordering Process

AX742X safety relief/pressure holding valve is composed of main valve and needle type regulating valve, guide valve, ball valve and nozzle system. The main valve body adopts full channel, direct current and streamline design, and adopts diaphragm or piston structure. This product sets the outlet pressure by setting the spring pressure of pressure regulating guide valve and adjusting the opening of needle valve, and stabilizes the outlet pressure through the feedback of nozzle system and control room.

This product uses needle-type regulating valve and guide valve to control water pressure independently. It does not need additional equipment and energy. It is easy to maintain and maintain. It is less affected by inlet pressure and flow. It has high accuracy of pressure control and reliable pressure reduction and stabilization.

Working principle

When the pipe feeds water from the inlet end, the water flows through the needle valve into the main valve control room, and the outlet pressure acts on the guide valve through the pipe. When the outlet pressure is higher than the set value of the guide valve, the guide valve closes and the control room stops draining. At this time, the main valve control room pressure rises and closes the main valve, and the outlet pressure no longer rises.

When the outlet pressure drops to the pilot valve setting pressure, the pilot valve opens and the control room drains downstream. Because the displacement of the pilot valve is greater than the water intake of the needle valve, the pressure of the main valve control room drops, and the inlet pressure makes the main valve open. Under steady state, the inlet and drainage of the control room are the same, the opening degree is constant, and the outlet pressure remains unchanged.

The outlet pressure can be set by adjusting the guide valve spring.

Work characteristics

1, pressure control is stable and reliable. The pilot valve and main valve work continuously, and the downstream pressure changes continuously and smoothly.

2, easy to operate. After the working pressure is adjusted, the main valve automatically adjusts when the upstream pressure or flow changes, and the downstream pressure is stabilized.

3, the valve body uses a full channel, DC, streamlined design. The hydraulic loss is small and the energy saving effect is good.

Functions and uses

The valve is generally installed in the upstream of the water supply network system to achieve the function of reducing pressure and stabilizing the downstream pipe network or device.

This series of valve products are widely used in high-rise buildings, living areas or other water supply network system hydraulic control.
