A butterfly valve is a type of flow control device, typically used
to regulate a fluid flowing through a section of pipe.
The valve is similar in operation to a ball valve. A flat circular
plate is positioned in the center of the pipe.
The plate has a rod through it connected to an actuator on the
outside of the valve. Rotating the actuator turns the
plate either parallel or perpendicular to the flow. Unlike a ball
valve, the plate is always present within the flow,
therefore a pressure drop is always induced in the flow regardless
of valve position.
