Applications

Ball check valves are commonly used in applications where low flow resistance and reliable backflow prevention are necessary, such as in water treatment plants, pumping systems, and process piping systems. They are often used in situations where the fluid needs to flow in only one direction, such as in fuel lines, chemical processing systems, and air compressors.

Tips: What is a flanged ball check valve?

A flanged ball check valve is a type of check valve that is designed to prevent backflow of fluids in pipelines. It is called "flanged" because it is installed between two pipe flanges using bolts and nuts, which provide a secure and leak-proof connection.

The valve has a ball-shaped disc inside, which moves up and down in response to the fluid flow. When the fluid is flowing in the desired direction, the ball is pushed upwards, allowing the fluid to pass through the valve. When the flow reverses, the ball is pushed back into the seat, creating a tight seal that prevents backflow.

Flanged ball check valves are commonly used in a wide range of industrial applications, including water and wastewater treatment, chemical processing, oil and gas, and mining. They are preferred in applications where a tight seal and low-pressure drop are important, and where frequent maintenance or repair is not required.

Flanged ball check valves are available in a variety of materials, including cast iron, stainless steel, bronze, and PVC, to suit different types of fluids and operating conditions. They can be designed for specific pressure and temperature ranges, as well as different sizes and end connections.
