Foot Valve

As a Foot Valve Supplier in Dubai, we provide suction-end non-return valves with built-in strainers for pump intakes. A foot valve sits at the end of the suction line, allowing fluid to enter the pump on startup and closing when the pump stops so the line stays full. By holding prime and screening debris, these valves help pumps start reliably, run quietly, and last longer in water, desalination, power, and industrial services.

How Foot Valves Work

Foot valves act as pump suction check valves that combine non-return and straining functions:

• Opening: On startup, inlet pressure lifts the disc and fluid enters the pump through the built-in screen.
• Closing: When the pump stops, the disc returns to the seat, holding liquid in the line and keeping the pump primed.
• Debris protection: The strainer blocks stones, shells, and solids from entering the pump.
• Seating options: Soft elastomer seats improve tight shutoff at low differential pressures.
• Spring assist: Optional spring-loaded designs ensure quick disc closure, preventing backspin and reverse flow.

Foot Valve Benefits

• Maintains pump prime to reduce startup time and wear on seals and bearings
• Prevents reverse flow and backspin, protecting pumps and motors
• Large open-area strainers minimize pressure loss and extend cleaning intervals
• Soft seat and optional spring assist improve shutoff at low pressure differentials
• Straightforward service with a removable screen and bottom drain
• Spare screens and repair kits available for extended service life
