A Butterfly Control Valve is a rotary valve designed to regulate the flow of gases or liquids within a piping system by rotating a disc 90 degrees to permit or restrict flow. These valves, including concentric, double-eccentric, and triple-eccentric types, can start, stop, slow, or throttle flow and adjust the flow passage size in response to controller signals for precise control. Equipped with pneumatic or electric actuators, they enable rapid shut-off, regulation, emergency shut-off, fail-safe shut-off, operation in harsh environments, and remote control, offering enhanced efficiency and responsiveness.
