Pneumatic butterfly valves are powered by compressed air. As compressed air enters the pneumatic actuator, it drives internal components such as pistons or rack and pinion mechanisms to move, which in turn rotates the valve stem and butterfly disc to open or close the valve. The integration of a valve positioner enables precise control over the butterfly disc's rotation angle, allowing for accurate regulation of pipeline media parameters including flow rate and pressure.
The pneumatic wafer butterfly valves have a broad application scope spanning municipal engineering, industrial manufacturing, and public utility systems. Primarily designed for the on-off control and flow regulation of fluid media, they are particularly well suited for applications with space constraints and automated operation requirements.
