Differential pressure 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.
