A foot valve is a purpose specific check valve. Designed for immersion in a well, tank, or other liquid containing vessel, it serves as a one-way inlet valve on piping leading to the suction side of a pump. Foot valves and their connected piping will extend downward from the pump suction elevation. The purpose of the valve is to maintain prime on the pump by preventing the water column in the suction line from collapsing, due to gravity, and draining all the liquid from the suction side of the pump system.

For industrial applications, there are numerous versions of foot valves available in varying sizes, capacities and materials of construction. The function of the valve is simple, so the key selection criteria can be focused on features that will contribute to longevity and reduce or eliminate any maintenance burden.

The data sheet below provides some good illustrations of a foot valve and how it is installed. Share your fluid processing and control challenges with application experts, combining your process and facility knowledge with their product application expertise to develop effective solutions.
