Type -- The bottom valve, also known as the check valve, is a low pressure flat valve .
Function -- The pump is to ensure that the liquid flows in one direction in the suction line, allowing the pump to work properly.
When the pump bottom valve is intermittently stopped, the liquid cannot be returned to the water source tank, and the suction pipe is filled with liquid to facilitate the start of the pump.
Comfortable Design -- Professionally and practically designed with good working performance.
The pump bottom valve is light in weight, strong in resistance, easy to install, not easily deformed, and compact in structure.
