The pneumatic butterfly valve is a self-controlled pneumatic butterfly valve with a three-eccentric structure of a metal sealing valve. The pneumatic butterfly valve shaft adopts an integrated design to prevent the displacement of the valve shaft due to the pressure of the pipeline. The valve is a three-eccentric structure, so that the valve is completely separated from the valve seat at the moment of opening, and the valve seat is less prone to wear.
