Butterfly Valve Basics
Butterfly valves are a family of valves called quarter-turn valves that feature a rotating disc (the “butterfly”) fixed to a valve stem. The entire valve is made up of a valve body, disc, stem, seat, and use handles, gears, or automatic actuators for operation. The internal disc pivots on a center axis when the valve stem is turned, allowing 90° of movement – fully open or closed. Butterfly valves, unlike gate valves, are also a popular choice for throttling & regulating flow with actuation.
