IFAN brass foot valve

Production Materials

The IFAN brass foot valve is primarily constructed from high-quality brass, known for its excellent corrosion resistance, durability, and suitability for water applications. The internal components, such as the seal and spring, are typically made from rubber (NBR or EPDM) or thermoplastic materials to ensure a tight seal and resistance to wear. The strainer or filter component is often made from stainless steel or brass to prevent debris from entering the system.

Production Process

1. Material Selection: High-grade brass is selected for the valve body due to its corrosion resistance and strength.
2. Casting: The brass is cast into the desired shape for the valve body and strainer.
3. Machining: Precision machining ensures smooth surfaces and proper fitting of components.
4. Component Manufacturing: Internal parts like the seal, spring, and strainer are manufactured to exact specifications.
5. Assembly: The valve body, seal, spring, and strainer are assembled into a complete unit.
6. Quality Testing: The valve undergoes rigorous testing, including pressure tests, leak tests, and functional checks, to ensure reliability and performance.

Working Principle

The IFAN brass foot valve operates as a check valve installed at the bottom of a pump’s suction line. It allows fluid to flow into the pump when the pump is operating, but prevents backflow when the pump is turned off. The valve opens when the pump creates suction, lifting the internal seal or flap. When the pump stops, the seal closes due to gravity or spring action, preventing fluid from flowing backward and maintaining prime in the pump.

Advantages

1. Corrosion Resistance: Brass construction ensures excellent resistance to rust and corrosion, making it ideal for water applications.
2. Maintains Pump Prime: Prevents fluid from flowing backward, ensuring the pump remains primed and ready for operation.
3. Debris Protection: The built-in strainer prevents debris from entering the pump and causing damage.
4. Durable Construction: High-quality brass and internal components ensure long-lasting performance in harsh environments.
5. Easy Installation: Designed for simple installation at the bottom of suction lines.
6. Low Maintenance: Robust design with minimal moving parts reduces the need for frequent maintenance.
7. Versatility: Suitable for a wide range of fluids, including water, chemicals, and industrial liquids.

The IFAN brass foot valve is a reliable and efficient component in pump systems, ensuring efficient operation, preventing backflow, and protecting pumps from damage. Its corrosion resistance, durability, and ease of use make it a popular choice across various industries.
