Understanding Wafer Ball Valves

A wafer ball valve—also known as a thin-profile or compact ball valve—is an industrial valve that regulates the flow of media in a pipeline or enables rapid opening and closing by rotating a spherical closure element 90 degrees around the valve body’s central axis. Featuring a compact design without integrated flanges, it is secured between two pipeline flanges using double-ended studs (bolts).

What is a wafer-style ball valve? How does it differ from a standard ball valve?

A wafer-style ball valve controls fluid flow by rotating a valve core (the ball). It is commonly used for applications such as fluid shut-off, distribution, and flow direction changes. It features a “wafer” design, meaning the valve is clamped between two pipe sections using bolts, eliminating the need for the extra space required by traditional flange connections. Thanks to its unique structural design and excellent performance, it is widely used in various piping systems.
