Butterfly Valves

A Butterfly valve is a quarter-turn rotational motion valve, that is used to stop, regulate, and start flow.  Butterfly valves are easy and fast to open.  A 90° rotation of the handle provides a complete closure or opening of the valve.  Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open.
