FOOT VALVE VALVE

A foot valve is a type of check valve that is typically installed at the bottom of a suction line in a pump system, such as in wells, sumps, or reservoirs. Its design includes a hinged flap or a spring-loaded ball that opens when the pump operates, allowing fluid to enter the suction pipe. Once the pump is turned off, the valve closes under its own weight or the action of a spring, preventing backflow and maintaining prime in the pump. Foot valves are crucial in preventing the pump from losing prime and ensuring efficient operation by keeping the suction line filled with fluid. They are commonly used in applications where continuous or intermittent pumping is required, such as in agriculture, irrigation, dewatering, and industrial processes involving liquid transfer.
