Product Summary

Ball type non return valve is also named as ball check valve. It is a non return valve in which the closing member, the movable part to block the flow, is a spherical ball. In some (but not all) ball check valves, the ball is spring-loaded to help keep it shut. For those designs without a spring, reverse flow is required to move the ball toward the seat and create a seal. The interior surface of the main seats of ball check valves are more or less conically-tapered to guide the ball into the seat and form a positive seal when stopping reverse flow.

Ball type non return valve is often very small, simple, and cheap. They are commonly used in pumps. The balls are most often made of metal, also other materials. There are similar check valves where the disc is not a ball, but some other shape, such as a poppet energized by a spring. Ball type non return valve should not be confused with ball valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow.
