The Flomatic 4108E 4" 60SE Enviro foot valve is a stainless-steel spring-loaded foot valve designed for very high-capacity pumping systems. This model features a Nitrile (Buna-N) seal, a bronze poppet, a stainless-steel spring, and a corrosion resistant strainer and 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 strainer helps keep larger debris out of the suction line.

Construction: The Flomatic foot valves check 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 stops and starts. In addition, the valves have been uniquely designed to absorb some of the hydraulic water shocks associated with well water pumping when the check valve installation instructions are followed below.

The foot valves screen protects the valve and the pumps internal parts as well as the system from harmful debris. The screen slides over the valve and is held in place with screws and acts as a filter for large particles, though a finer filter can be added after the pump. The screen is design with a large flow area (approximately three-time pipe area) to minimize flow losses. Flomatic foot valve screens are removable for cleaning and or replacement.

The stainless-steel body, bronze poppet, spring, and hardware provide excellent resistance to corrosion and wear in demanding water system environments.

Applications: Municipal, industrial, agricultural, and other large scale suction lift and water transfer systems.
