    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.

    Ball check valve applications

    Tips: How does a ball check valve work?

    When fluid flows through the valve, the ball is pushed away from the seat and allows the fluid to pass through. When the flow stops, the ball is pushed back against the seat by the force of gravity or the pressure of the fluid, which prevents backflow.

    The ball check valve is commonly used in plumbing, wastewater treatment plants, and many other industrial applications where the prevention of backflow is critical. The valve is simple and reliable, and it requires minimal maintenance, making it a popular choice for many different applications.
