What Is a Wafer Butterfly Valve?
A wafer butterfly valve is a compact quarter-turn valve designed to be installed between two flanges in a piping system. It is widely used for shut-off and flow regulation in water treatment, HVAC, fire protection and general industrial service.
Compared with heavier valve designs, wafer butterfly valves offer a lighter body, shorter face-to-face dimension and more economical installation. They are especially suitable for low to medium pressure applications where space-saving layout and reliable sealing are important.
Wafer butterfly valves can be supplied with different body materials, disc materials, seat options and actuation methods to match media conditions, temperature requirements and project standards.
