Wafer-Style Butterfly Valve


Most wafer-style butterfly valves are engineered with four holes that align with the connected pipeline. The valve is designed to clamp between two flanges in your pipe work. Most wafer butterfly valves fit the majority of flange standards.

Why is it called a butterfly valve?
Butterfly valves are quarter-turn valves, meaning they go from completely open to completely closed in 90 degrees. The “butterfly” name comes from the fact that the disc, or “wings,” moves around a central axis, which acts like the body of a butterfly. But there is much more to butterfly valves than the central disc.
