A Pneumatic Butterfly Valve is an essential component in industrial systems used to control the flow of various types of fluids, including gases, liquids, and steam. Known for its quick action and efficient design, this valve operates with the help of compressed air to control the position of a rotating disc, known as the butterfly, inside the valve body. This article explores the working principle, advantages, applications, and key components of pneumatic butterfly valves.

    Working Principle of Pneumatic Butterfly Valve

    The pneumatic butterfly valve operates by using a pneumatic actuator to rotate a disc (butterfly) inside the valve body. This disc, typically round and mounted on a shaft, can rotate 90 degrees to either fully open or close the valve, depending on the position of the actuator. The actuator is powered by compressed air, which controls the valve’s opening or closing.
