Call Us Now! The Plastic Foot Valve is a critical component in water pumping and fluid transfer systems, specifically designed to prevent backflow and maintain prime in the pump. Installed at the inlet end of a suction pipe, this valve ensures that water or fluid flows in only one direction—from the source to the pump—without returning when the pump is turned off.
Manufactured by Ashok Polymers using high-grade engineering polymers, the Plastic Foot Valve offers superior resistance to corrosion, chemicals, and wear. Its lightweight yet durable construction makes it an economical and highly reliable choice for agricultural irrigation, domestic water supply, and industrial pumping applications.
With its built-in strainer, the valve also prevents debris, sand, and other particles from entering the pumping system, significantly extending pump life and ensuring uninterrupted operation.
What is a Plastic Foot Valve?
A Plastic Foot Valve is a type of check valve that operates at the bottom end of a suction pipe in a pump system. It functions similarly to a one-way valve, allowing fluid to flow into the pipe when suction is applied, but automatically closing when the pump stops to prevent the liquid from flowing back.
The valve is typically made of durable plastic materials such as PP (Polypropylene) or UPVC, making it corrosion-resistant and ideal for use in fresh water, saline water, and even certain chemical solutions. The built-in strainer mesh or grill at the base ensures that larger particles do not enter the system, protecting pumps from clogging and wear.
How Does It Work?
The operation of a Plastic Foot Valve is straightforward but crucial to the efficiency of a pumping system:
The valve is attached at the very bottom of the suction pipe, submerged in the water source such as a well, pond, or tank.
When the pump starts, suction creates a pressure difference that lifts the internal disc or flap of the valve, allowing water to flow upward into the pipe.
The internal disc or flap automatically closes due to gravity and back pressure from the water in the pipe.
The integrated strainer prevents leaves, pebbles, sand, and other debris from entering and damaging the pump or pipeline.
