GH-4004 Brass water foot check valve

The brass water foot check valve is a vital component in pump suction systems, designed to prevent backflow and maintain prime in pipelines, ensuring efficient pump operation. Installed at the bottom of suction lines in wells, tanks, or reservoirs, this valve features a swing or spring-assisted check mechanism that opens under suction pressure to allow fluid intake and automatically closes when the pump stops, blocking reverse flow and retaining liquid within the system.
Crafted from corrosion-resistant brass, the valve withstands prolonged exposure to water, mild chemicals, and abrasive particles, making it ideal for agricultural irrigation, residential water supply, and industrial fluid transfer applications. Its integrated strainer screen (often stainless steel) filters out debris, sediment, and foreign particles, protecting pumps and downstream equipment from damage.
