Threaded Foot Valves
Threaded Foot Valve
A threaded foot valve is a check valve fitted to the lowest end of the pump suction line, featuring an integral strainer. When the pump stops, it prevents backflow of water from the well or tank into the suction line, ensuring the pump can draw fresh water with each start; the strainer prevents coarse particles from entering the pump.
Brass body models with stainless steel springs and NBR seals are available from 3/4″ to 6″, in pressure classes PN10 and PN16. Spring, full bore and domed strainer options are offered.
