A butterfly valve is a device used to interrupt or regulate fluid flow by increasing or decreasing the cross-section with a disc. As the flow area decreases, pressure loss increases, reducing flow. Butterfly valves have low pressure loss when fully open. The relationship between the flow area and the disc's rotation angle is not linear. Butterfly valves are commonly used in air ducts, liquid pipelines, and mechanical applications. Among butterfly valve types, double or triple offset butterfly valves offer less seat wear. This type of butterfly valve features an offset stem (double) and, if applicable, a third offset in the seat. The construction of a butterfly valve makes it an economical valve compared to other types. Additionally, a butterfly valve is more economical for large sizes; its construction makes it easy to handle and install. A notable advantage of butterfly valves is the absence of cavities where solids could accumulate, hindering valve maneuverability. On the other hand, a disadvantage of a butterfly valve is its performance under high working pressures."}
