CGIS Datasheets for Butterfly Valves

Butterfly valves control flow through a circular disc or vane by turning the valve's pivot axis at right angles to the direction of flow in the pipe. They are normally used as throttling valves to control flow.

Product Name Notes
Also known as a triple-eccentric design, there are three key offsets involved in creating this feat of engineering. First, the disc is placed forward from the access of stem rotation.
Instead of using a large ball as the closing mechanism, a Butterfly Valve can use a disk which enables quick shutoff and drastically reduces the overall footprint of the valve.
