1. Simple structure: The Pneumatic Butterfly Valve consists of a valve body, a valve seat, a valve plate, a pneumatic actuator and connecting parts. It has a compact structure and is easy to install.

2. Adjustable flow: By adjusting the opening of the pneumatic actuator, precise control of the fluid can be achieved and the flow rate can be adjusted.

3. High sealing performance: The valve seat adopts a three-eccentric structure design, which has a small contact area with the valve plate and good sealing performance, which can effectively prevent leakage.

4. Strong corrosion resistance: The valve body and valve plate are usually made of corrosion-resistant materials and can adapt to the working environment of various corrosive media.

5. Rapid opening and closing: Pneumatic actuators have the characteristics of rapid response and can quickly open and close valves, which is suitable for occasions requiring frequent operations.
