The Flomatic 4091XSSF 10" 80S6F stainless-steel foot valve is a heavy-duty, spring-assisted design for demanding water and process applications requiring corrosion resistance and elevated temperature capability. It features an all 316 stainless-steel body, stainless-steel spring, poppet, stem, screen, and a Viton seal. Rated 400 psi and 400°F (200°C).

Specifications:

Max Pressure: 400 psi

Max Temperature: 400°F (200°C)

Body: 316 stainless-steel

Seal: Viton

Spring: 316 stainless-steel

Screen: 316 stainless-steel

Connection: 10" FNPT threaded (ANSI B1.20.1)

Weight: 190.0 lbs

Operation: The 80S6F stainless-steel foot valve maintains pump prime and prevents backflow under high-pressure and high-temperature conditions. The spring-assisted poppet closes rapidly as flow reverses to limit water hammer.

Construction: All 316 stainless-steel construction provides superior resistance to corrosion and erosion. The stainless-steel screen offers a large open area to reduce head loss and protect the suction line from debris. FNPT threaded ends allow simple installation.

Applications: High-pressure and high-temperature stainless-steel water and process systems, industrial pumping installations, and other applications needing a robust stainless-steel foot valve for maintaining prime and reducing backflow.
