Foot valves are energy-efficient check valves typically installed at the bottom of pump suction pipes to prevent backflow of fluid into the water source. The valve cover is designed with multiple inlet holes and reinforcing ribs, which help reduce clogging and ensure smooth operation. These valves are widely used in industrial, water treatment, and household applications.

**Working Principle:**
The foot valve consists of a bonnet, disc, bushing, and seal ring. When the pump is operating, water enters the valve body through the bonnet, pushing the disc open under pressure. Once the pump stops, the pressure in the outlet pipe closes the disc instantly, preventing backflow and ensuring efficient pumping while minimizing water loss.
