A butterfly valve is a type of quarter-turn valve used to regulate, isolate, or start and stop fluid flow in a piping system. It consists of a circular disc or plate mounted on a rotating shaft. When the handle or actuator turns the shaft 90 degrees, the disc moves from a fully closed to a fully open position, allowing flow through the valve. The disc remains in the flow path even when open, which means there is always a slight pressure drop. Butterfly valves are known for their compact design, fast operation, and cost-effectiveness, especially in large-diameter pipelines. They come in various types, such as wafer, lug, and double or triple offset styles, depending on the pressure and sealing requirements. These valves are widely used in industries such as water treatment, HVAC, chemical processing, oil and gas, and food and beverage, due to their reliability, low maintenance, and easy installation.
