It’s all about the point! Selection and application control of large diameter water meters.

The bottom valve is installed at the lowest end of the pump suction pipe to prevent the water in the suction pipe from being drained after shutdown.

The three-way ball valve is a commonly used valve. Its main function is to control the flow direction of the fluid medium in the pipeline. This valve has the advantages of simple structure, convenient operation, and good sealing performance, and is widely used in various industrial pipeline systems.

Do not install the gate upside down (that is, with the handwheel downward), otherwise the medium will remain in the valve cover space for a long time, which will easily corrode the valve stem, and is contraindicated by certain process requirements. It is extremely inconvenient to replace the packing at the same time. Do not install rising stem gate valves underground, otherwise the exposed stem will be corroded by moisture.
