CPVC Foot Valve

A CPVC Foot Valve is a type of non-return (check) valve made from Chlorinated Polyvinyl Chloride (CPVC) material, installed at the suction end (bottom) of a pump’s suction line. It allows fluid to flow in only one direction—toward the pump—and prevents backflow when the pump is turned off. The CPVC Foot Valve is typically fitted with a strainer at the inlet to prevent debris, sediment, and solid particles from entering the pump system. This helps to maintain pump priming and protects internal pump components from damage.

We provide high-quality CPVC Foot Valve Supplier in India. The CPVC foot valve is located at the end of a pipeline. In addition to serving as a check valve, these also include a strainer attached to the open end of the valve. The CPVC Foot Valve supplier has a spring-assisted check valve. Whenever a pump is turned on, the tension of the pump column varies, and as a result, the valve opens. Whenever the pump is turned off, the valve responds by closing once again. As a result, the pump will not lose prime every time it is turned off due to leakage of fluid from the pump column.

High Corrosion Resistance
Made from CPVC material, offering excellent resistance to acids, alkalis, salts, and corrosive fluids.
Built-in Strainer
Integrated mesh strainer prevents debris and solid particles from entering the pump.
Non-Return Mechanism
Allows fluid flow in one direction and prevents backflow when the pump stops.
Maintains Pump Priming
Keeps the suction line filled with liquid, ensuring smooth pump startup.
Lightweight Construction
Easier to handle and install compared to metal foot valves.
High Temperature Capability
Suitable for fluid temperatures up to approximately 90°C.
Leak-Proof Sealing
Soft-seated sealing (EPDM/FKM) ensures tight shut-off and minimal leakage.
Low Cracking Pressure
Requires minimal pressure to open, improving suction efficiency.
Smooth Internal Surface
Reduces friction loss and improves flow efficiency.
Durable and Long Service Life
Non-metallic construction prevents rusting and scaling.
Multiple Connection Options
Available in threaded and socket (solvent weld) end connections.
