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.
