Foot Valve

In water treatment, chemical processing, semiconductor and industrial pumping systems, a failing foot valve can cause loss of pump priming, backflow, pump damage and costly production downtime. Metal foot valves often suffer from corrosion, unreliable sealing and frequent clogging — especially when submerged in acids, alkalis and aggressive chemical sumps. XITA plastic foot valves are engineered to solve these problems: manufactured from PVC, CPVC and PPH with ball-type and ball-core designs, they deliver reliable priming retention and backflow prevention with integrated strainer protection, excellent corrosion resistance, and significantly lower maintenance costs compared to metal alternatives.

As an experienced plastic foot valve manufacturer, we offer a complete range including ball type foot valves and ball core foot valves in sizes from DN15 to DN110 (1/2″ to 4″). Available with socket and threaded connections, EPDM or VITON seals, SUS304 springs, and pressure ratings up to PN16. All products feature integrated strainer screens to protect pumps from debris, and conform to DIN, ASTM, JIS, BS EN ISO1452 and ISO4422 standards, with SGS and CE certification.

Why Our Plastic Foot Valves Perform Better

Reliable Priming & Backflow Prevention

A free-floating ball core seats instantly against the precision-molded seal the moment pump flow stops, creating a leak-tight barrier that prevents backflow and maintains pump priming. This eliminates time-consuming re-priming before every start-up, protects pumps from dry-run damage, and ensures continuous operation in chemical dosing, water treatment and industrial suction lift applications.

Integrated Strainer Protects Pumps

Each foot valve features an integrated strainer screen that prevents solids, debris and large particles from entering the pump suction line, reducing impeller damage and clogging. The open-area screen design maximizes flow capacity while providing effective filtration, and the valve body can be easily removed for cleaning without dismantling the entire pipeline — minimizing downtime in sumps, tanks and open-water intake applications.

Corrosion Resistance for Submerged Service

Available in PVC, CPVC and PPH materials, our plastic foot valves withstand continuous submersion in acids, alkalis, salts, oxidizers and chemical solutions that rapidly corrode cast iron and steel foot valves. PPH models offer exceptional high-temperature chemical resistance and zero media contamination, making them suitable for semiconductor, pharmaceutical and high-purity processing where metal valves would fail quickly in corrosive sump environments.

Low Flow Resistance & Lightweight

The smooth internal bore and streamlined flow path minimize turbulence and pressure drop, with flow resistance 30% lower than cast iron foot valves — reducing pumping energy costs and improving suction lift performance. Our plastic foot valves weigh only 1/6 of cast iron equivalents, making installation and servicing in tanks, sumps and submerged locations far easier and safer, with total engineering cost 30–40% lower than metal valve systems.
