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 the difference between a ball check valve and a swing check valve?

A ball check valve uses a spherical ball to block reverse flow, while a swing check valve uses a hinged disc or gate. Ball check valves typically offer quicker closing times and are less likely to get stuck open compared to swing check valves.
