AX742X Pressure Safety Relief Valve 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. AX742X Pressure Safety Relief Valve has high accuracy of pressure control and reliable pressure reduction and stabilization.
 

AX742X Pressure Safety Relief Valve 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.
 

AX742X Pressure Safety Relief Valve  characteristics

1. AX742X Pressure Safety Relief Valve pressure control is stable and reliable. The pilot valve and main valve work continuously, and the downstream pressure changes continuously and smoothly.

2.  AX742X Pressure Safety Relief Valve is 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. AX742X Pressure Safety Relief Valvebody uses a full channel, DC, streamlined design. The hydraulic loss is small and the energy saving effect is good.

AX742X Pressure Safety Relief Valve Functions and uses

AX742X Pressure Safety Relief 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.

AX742X Pressure Safety Relief Valve is widely used in high-rise buildings, living areas or other water supply network system hydraulic control.
