    Installation Diagram

    Typical installation diagram of ball check valve


    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 ball check valve?

    A ball check valve, also called a ball non-return valve, uses a ball that sits in the flow path. When the flow is in the correct direction, the ball is pushed out of the way and fluid or gas can flow through the valve. When flow is reversed, the ball is forced against its seat and the valve closes. Ball check valves are commonly found in small pipe sizes and low-pressure systems. They are relatively inexpensive and easy to maintain, and they are often used in applications where a low flow rate is sufficient and where space is limited.
