Foot Valves
Foot valves are a form of check (non-return) valve fitted at the very bottom of a pump's suction line, submerged in the fluid being drawn. They serve two linked purposes: they let liquid flow upward into the suction pipe when the pump runs, and they close when the pump stops, trapping the column of liquid in the line so the pump stays primed and does not lose suction. Most foot valves include an integral strainer or screen at the inlet, which keeps leaves, stones, and other solids out of the suction pipe and away from the pump impeller, so the valve combines a non-return function with coarse filtration.
The closure is usually a spring-assisted or gravity disc/poppet, or a flap, seating against a body so that reverse flow shuts it. They are used on borewell, irrigation, fire-water, cooling, and general transfer pumps, and on tanks where a primed suction line must be maintained. Sizes commonly run from around ½"/15 mm up to large irrigation and fire-service bores, with threaded BSP/NPT, flanged, or hose-tail ends depending on the duty. A low cracking pressure and generous net free area through the strainer help keep suction losses (and NPSH penalties) down.
Bodies and screens are made in cast iron, gunmetal/bronze, brass, plastics (PVC/PP) for water and corrosive service, or stainless (CF8/CF8M) for hygienic and aggressive media; seats and discs use elastomer or metal-to-metal seating suited to the fluid. Strainer perforation is selected to balance debris exclusion against flow.
Himalay's MSME partners manufacture foot valves with seat-tightness and where applicable shell testing per BS EN 12266-1 / ISO 5208 as relevant, material traceability, and PED-CE (EU), SABER (Saudi Arabia), and NACE MR0175 (sour service) coordinated as part of the standard order flow where the duty requires it.
