Valve Introduction
The bottom valve is also called a check valve. It is a low-pressure flat valve. Its function is to ensure the unidirectional flow of liquid in the suction pipe, so that the pump works normally. When the pump stops intermittently for a short time, the liquid cannot return to the water source tank. The suction pipe is filled with liquid to facilitate the start of the pump.
