Thepneumatic butterfly valveis a versatile and reliable component used in various industries for controlling the flow of fluids or gases. It combines the simplicity of a butterfly valve with the efficiency and precision of pneumatic actuators, making it an essential tool in modern automation and fluid management systems. This article explores the function, applications, and advantages of the pneumatic butterfly valve, shedding light on why it is so widely used across industries.
What is a Pneumatic Butterfly Valve?
Apneumatic butterfly valveis a type of flow control valve that consists of a rotating disc, typically mounted in the center of the pipe. The valve is actuated by a pneumatic actuator, which uses compressed air to rotate the valve disc and regulate the flow of fluid through the valve. When the valve is open, the disc aligns with the pipe’s flow, and when it is closed, the disc obstructs the flow path, creating a seal. The pneumatic actuator can be a spring-return type, which automatically returns to its fail-safe position when the pneumatic supply is removed, or a double-acting type, which requires air supply for both opening and closing the valve.
