BUTTERFLY VALVE

• A butterfly valve is a valve that isolates or regulates the flow of a fluid.
• The closing mechanism is a disk that rotates.
• Operation is similar to that of a ball valve, which allows for quick shut off.
• 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.
