Operation: The 357 Foot valve is installed at the end of a suction line to help maintain prime and reduce reverse flow when the pump stops. The hinged leather seat swings open under forward flow and closes as flow reverses, helping to prevent backflow into the source and limit loss of suction.

Construction: A rugged cast iron body and strainer provide durability for low-pressure water service, while the hinged leather seat offers a resilient seating surface. The integral strainer helps keep larger debris out of the suction line, and the female threaded FNPT connection allows straightforward installation in threaded piping systems.

Applications: Shallow well, cistern, and other low-pressure water systems where a simple cast iron foot valve is needed to help maintain prime and prevent backflow.
