A ball valve is a quarter-turn rotation valve that uses a ball-shaped disk to stop or start flow through the valve. When the ball valve opens, the ball rotates so that the ball's port is in line with the valve body inlet and outlet. If the valve is closed, the ball turns so that the port is perpendicular to the flow openings of the valve body, and the flow stops.
A butterfly valve is a quarter-turn rotational motion valve that stops, regulates, and starts the flow using a disk. The disk is always in the passageway, but because it is relatively less thick, it offers little resistance to flow. The butterfly valve offers many advantages, including 90-degree rotation for fully open and fully closed and good control capabilities to control the flowing media in a process.
Both types of valves are used widely in industry and are available in a broad spectrum of materials, depending on their application. Each style valve has unique advantages when applied, and it is always a good idea to discuss your application with a valve expert.
