Foot Valves

Installed on the pump suction, Crispin Foot Valves prevent the pump column from draining upon pump shutdown. Silent during operating and normally closed, the valve has a center-guided disc with a Buna-N seat to provide a drip tight seal.

Design of Foot Valve, available in sizes 2 inches to 30 inches, evolved through a need for a valve that could provide positive sealing actions at various pressure ranges without seat damages, along with silent operation.

The Foot Valve, satisfies these requirements plus low head loss through its full ported area and heavy duty stainless steel basket screening.

The Buna-N O-ring, provides a drop-tight seal. As the pressure increases, the Buna-N O-ring is compressed slightly and the disc makes contact with the metal portion of the valve seat, preventing any further compression of the Buna-N O-ring. The Buna-N O-ring will continue to provide the “drop-tight seating” during the higher pressure ranges without damage from the increased pressure loading.
