A butterfly valve is a device used to shut off or regulate fluid flow by increasing or decreasing the cross-section using a disc. Reducing the flow area increases pressure drop, thereby reducing flow. Butterfly valves have a low pressure drop when fully open. The relationship between the flow area and the disc’s rotation angle is non-linear. Butterfly valves are typically used in air ducts, liquid pipelines, and mechanical applications. Among butterfly valve types, double or triple offset designs offer reduced seat wear. These feature an offset shaft (double) and, if applicable, a third eccentricity in the seat. Their construction makes butterfly valves economical compared to other types, especially for large sizes. They are also easy to handle and install. A key advantage is the lack of cavities where solids can accumulate and impede operation. Conversely, a disadvantage is their performance under high operating pressures.
