A foot valve, in relation to a well, is a check valve at the bottom of a well to keep the fluid from running back into the well from the pump when the pump is not running. If the check valve does not hold the fluid, the pump will lose it’s prime and will not pump the fluid.
Design Features:
Our Foot Valves are designed for liquid service and are ideal for municipal and industrial applications.
Size: 2″ thru 24″
End Connections: Flanged
Body Materials: Cast Iron, Cast Ductile Iron, Cast Steel, Cast Stainless Steel
Trim Materials: Stainless Steel, Buna-N
Pressure Ratings: ASME Class 125 & 150
Elastic Swing Foot Valve
The Elastic Swing Foot Valve is standard with a ductile iron body, ASME Class 125 flanges and is suitable for municipal and industrial applications. The internal body is epoxy coated. Special coatings are available upon request. The one-piece molded disc has a steel reinforced insert to ensure closure, but while in the open position will allow 100% uninterrupted flow. The one-piece disc hinge and flapper can be repaired without removal of the valve from the line. The Elastic Swing Foot Valve is designed for continuous flow applications and is not recommended for reciprocating pumps. The Elastic Swing Foot Valve can be installed in a vertical or horizontal pipeline.
Silent Seat Foot Valve
The Globe Silent Seat Foot Valve has low head loss through its full ported body area and heavy duty stainless steel basket screening. As pressure increases, the Buna-N Quad Ring is compressed slightly and the disc makes contact with the metal portion of the valve seat, preventing any further compression of the ring. The Buna-N Quad Ring will continue to provide “drop-tight seating” during the higher pressure ranges without damage from the increased pressure loading. A foot valve should be used with basket strainers and check valves.
STANDARD FEATURES
The seating design provides positive shut-off at all pressure ranges without additional loading on the seal.
A Buna-N Quad Ring is standard on Foot Valves size 6” and larger. Valve comes standard with 1/8” perf. Stainless Steel Screen. Options are available.
Heavy duty stainless steel screening, with flow area 3 to 4 times that of pipe area. Silent operation, by design of disc, stroke and linear closing characteristics.
