Steriflow Food & Beverage FB6903 3A-Sanitary Approved Check Valves

Use the Steriflow FB6903 when it's critical to prevent your process liquid from flowing in the wrong direction in sanitary applications. The valve is held open by the liquid flowing in the right direction. When flow stops, it forces the plug against its seat by the spring, and will close against reversal of the liquid flow.

The FB6903 is 3A-sanitary approved under standard 58-01, and can be disassembled easily for cleaning or repairs.
