Introduction
The IFAN PVC Foot Valve is a type of check valve that is designed to be installed at the bottom (foot) of a vertical pipe, typically in pump suction lines. Its primary function is to prevent backflow and protect pumps from damage caused by water or fluid reversal. The IFAN PVC Foot Valve is widely used in various industries, including agriculture, water treatment, and industrial fluid handling systems.
Production Materials
The IFAN PVC Foot Valve is constructed from PVC (Polyvinyl Chloride), a material that provides excellent resistance to corrosion, UV degradation, and many types of chemicals. This makes it an ideal choice for applications that involve water, chemicals, and other non-corrosive liquids.
- Valve Body: The body of the foot valve is made from durable PVC
- Strainer: The foot valve is often equipped with a stainless steel strainer or PVC mesh to filter out debris and prevent clogging, protecting the pump from damage.
- Seals: High-quality NBR (Nitrile Butadiene Rubber) or EPDM seals are used to ensure a tight and leak-free connection, preventing fluid loss and maintaining the valve’s efficiency.
Operating Principle
The IFAN PVC Foot Valve operates as a check valve, preventing backflow of fluid and ensuring a continuous, unidirectional flow into a pump or pipeline:
- Flow Control: The valve is typically placed at the inlet (foot) of a suction pipe to prevent the backflow of liquid when the pump is turned off.
- Valve Disc Mechanism: Inside the valve, a disc or flap mechanism moves up and down based on the pressure of the incoming flow. When there is adequate suction or pressure, the disc opens, allowing fluid to enter the pipe. When there is no pressure or reverse flow, the disc closes, creating a seal to stop backflow.
- Strainer: Many foot valves also feature a built-in strainer that filters out debris from the water or fluid
