Flomatic 4172E 1¼" 333E Enviro – Stainless Steel Foot Valve

The Flomatic 4172E 1¼" 333E Enviro foot valve is a stainless-steel spring-loaded foot valve designed to help maintain pump prime, prevent backflow, and protect suction lines from debris. This model features a Nitrile (Buna-N) seal, a high-strength acetal poppet, a stainless-steel spring, and a corrosion-resistant tapered stainless-steel strainer. The 4172E is rated for a maximum working pressure of 250 psi and a maximum temperature of 180°F (80°C).

Operation: Flomatic foot valves are designed to give years of trouble-free operation without maintenance when properly installed and in a properly selected pumping application with regards to flow and maximum system pressures. The internal spring-loaded poppet closes quickly to reduce reverse flow and loss of prime, while the integral tapered strainer helps prevent debris from entering the suction line.

Construction: The Flomatic 333E foot valve body has been constructed to handle the rated system flow and pressures as stated and to assure that the pump does not lose its prime between cycles. The design also helps absorb water hammer and hydraulic shock that may occur in well and irrigation systems.

The tapered stainless-steel strainer protects internal components from harmful debris and provides a large open area to minimize flow restriction. It is removable for cleaning or replacement.

Applications: Light commercial wells, residential water systems, irrigation systems, and general suction-lift applications.
