A Butterfly Valve controls flow using a circular disc positioned within the valve body. Rotating the disc through a quarter turn allows the valve to move between the fully open and closed positions, while intermediate positions can be used for flow regulation where appropriate.

Butterfly valves are widely used because of their compact construction, relatively low weight and simple operation, particularly in larger-diameter pipelines where space and installation requirements are important considerations.

The pictured valve features a lever-operated design with a notched position plate, allowing the disc position to be manually selected and secured.
