Foot Valves are specialty one-way check valves installed at the bottom intake of a pump suction line. Equipped with an integral heavy-duty strainer screen, a Foot Valve serves two indispensable functions: preventing pumped liquid from draining back into the well or sump when the pump shuts off (maintaining pump prime), and filtering out damaging debris, stones, and floating solids.
Zeron Fastners manufactures premium industrial Foot Valves in Cast Iron, Ductile Iron, Cast Steel, and Stainless Steel (SS 304 / SS 316). Designed with hydrodynamically contoured internal waterways and resilient NBR/EPDM seating, our foot valves minimize head loss, prevent pump cavitation, and ensure positive bubble-tight shutoff against backpressure.
