Introduction to Butterfly Valves
Butterfly valves are quarter - turn rotational motion valves used to stop, start, and regulate fluid flow. They consist of a circular disc that rotates on a shaft within a pipe. When the disc is parallel to the flow direction, the valve is fully open, allowing maximum flow. As the disc rotates to a perpendicular position, the valve closes, blocking the flow.
Butterfly valves are known for their simplicity, low cost, and relatively small size compared to other types of valves. They are widely used in various industries such as water treatment, HVAC (heating, ventilation, and air - conditioning), chemical processing, power generation, and food and beverage. Their ability to handle large volumes of fluid with relatively low pressure drop makes them a popular choice in many applications.
