Introduction
A butterfly valve is a type of flow control device used to isolate or regulate the flow of fluids in a piping system. It features a disc that rotates within the pipe, allowing for quick shut-off operations. Unlike ball valves, the disc remains in the flow path, which causes a pressure drop regardless of the valve position. Butterfly valves are known for their cost-effectiveness, lightweight design, and ease of installation, making them a popular choice in various industries such as water supply, industrial, and residential applications.
