Foot Valve

A foot valve is a type of valve that is used in pumping systems to prevent backflow of fluid. It is typically installed at the bottom of a suction line to ensure that the pump remains primed and does not lose its prime when it is turned off.

Foot valves are designed with a built-in check valve mechanism that allows fluid to flow in only one direction, typically from the suction line into the pump. This check valve prevents the fluid from flowing back into the suction line when the pump is not in operation, thereby maintaining the prime.

Foot valves are commonly used in applications where the pump is located above the fluid source, such as in wells or underground tanks. They are also used in irrigation systems, water supply systems, and other pumping applications.

In summary, a foot valve is a nonpowered valve that is used to prevent backflow and maintain the prime in pumping systems. It is part of the Valves, Nonpowered supply class and the Valves supply group.
