In fluid control systems where the pump is located above the fluid level (negative suction head), maintaining the “prime” is essential for operational reliability. HVAC Foot Valves are a specialised type of Non-Return Valve (NRV) installed at the very bottom of the suction line. They combine a check mechanism with a strainer to prevent backflow and block debris.
At FIFFCO GLOBAL LTD, we supply industrial-grade Foot Valves designed to ensure your pumps never run dry. Engineered for the UK market, our valves provide a robust solution for retrieving water from underground cisterns, break tanks, and wells without the risk of air locking the system.
Our Foot Valves are constructed to withstand the rigours of continuous immersion and suction pressure. We prioritise corrosion resistance and filtration efficiency in our design:
Unlike standard inline check valves, the Foot Valve is exclusively designed for the submerged intake of a suction line. They are critical components in:
Sourcing reliable suction equipment is vital to prevent pump burnout. Fiffco provides the assurance MEP contractors need.
The primary use is to maintain pump prime. By preventing water from flowing back into the tank when the pump stops, the valve ensures the suction pipe remains full of liquid. This prevents the pump from drawing in air (running dry) upon restart.
Many of our Brass Foot Valves meet WRAS requirements for use with potable (drinking) water. However, as specifications vary by model and mesh type, please check the specific product datasheet or consult our sales team to ensure compliance with Water Regulations.
Foot Valves are designed strictly for Vertical Installation at the bottom of a suction pipe. They must be submerged well below the minimum water level to prevent vortexing (drawing in air) but kept slightly off the tank floor to avoid sucking up settled sediment.
Don’t risk pump failure or air locks in your suction lines. Ensure continuous prime and effective filtration with Fiffco’s high-performance Foot Valves.
