A butterfly valve is a type of quarter-turn valve that operates by rotating a disc laterally, which opens and closes the flow through the valve. It is named after its resemblance to the flight of a butterfly due to the disc's motion. These valves are versatile and can be used in various applications, including water, air, steam, and slurry systems. Butterfly valves offer several advantages such as easy operation, low maintenance, and a compact design.
