Product Description

800X differential pressure bypass balancing valve consists of a main valve, differential pressure control pilot valve, Needle Valve, Ball Valve, micro filter and pressure gauge to form a hydraulic control take-over system. Through the specially designed pilot valve control chamber, the pressure change signals are compared, the main valve opening signal is output, and the main valve opening is controlled, thereby controlling the inlet and outlet pressure difference of the main valve at the set value. Its working principle is that when the pressure difference between the inlet and outlet of the main valve changes, the pressure difference between nozzle A and nozzle B changes, which changes the opening of the pilot valve. When the pressure difference is large, the opening of the pilot valve is large, and the water leakage from the control room through the C pipe increases. The pressure in the main valve control room decreases, the opening of the main valve increases, and the pressure difference between the inlet and outlet of the main valve becomes smaller. On the contrary, if the pressure difference between the inlet and outlet of the main valve becomes smaller, the opening of the toilet pilot valve becomes smaller, and the main valve control cable pressure rises, pushing the main valve opening to decrease and causing the main valve pressure difference to increase. This negative feedback effect stabilizes the pressure difference between the inlet and outlet of the main valve at the set value. Setting the needle valve opening and pilot valve spring pressure can set the pressure difference between the inlet and outlet of the main valve. This product uses hydraulic self-control, does not require other devices and energy, and is easy to maintain.

Pressure Differential Bypass Balancing Valve

The differential pressure bypass balancing valve is a Special Valve that can be used to connect fire water and domestic water in parallel to adjust the water supply direction. The differential pressure bypass balancing valve sounds complex in structure, but it is not laborious to install. So what are the installation specifications for the differential pressure bypass balancing valve?

1. Check the status of the differential pressure bypass balance valve. It should be ensured that all types of valves such as elastically seated gate valves, ball valves, and needle valves are in a full-pass state before use.

2. Observe the pressure between the water supply and return pipes, adjust the pilot valve of the differential pressure bypass balance valve according to the pressure difference, loosen the top cap on the pilot valve, use an adjustable wrench to rotate the top of the screw, and look from top to bottom. , rotating clockwise can increase the pressure difference, while rotating counterclockwise can reduce the pressure difference. Rotate according to the value to achieve the required pressure difference and fix the top cover of the screw.

3. If you want to adjust the switching speed of the main valve, you can adjust the needle valve. Clockwise rotation will slow down the movement, and counterclockwise movement will speed up. Under normal circumstances, the needle valve has been set and we do not need to adjust it.

4. The differential pressure bypass balance valve is only suitable for use on pipelines with one-way flow and should be placed on pipelines with one-way flow media.
