What is a butterfly valve?

Butterfly valve, named after its rotating disc that opens or closes the valve, is a quarter-turn rotary motion valve that is often used in large valve applications with tight spaces. While its most basic function is to start, stop, and regulate the flow of fluids just like other valves, a butterfly valve is often preferred over other valves because it opens and closes faster and requires less material and civil works. Furthermore, it is smaller and compact, making it versatile for use in piping systems.
