The butterfly disc of the ABO AC052D+924B pneumatic wafer butterfly valve is installed along the diameter direction of the pipeline. Within the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis. The initial position of the valve is determined based on actual requirements. When the valve rotates 90° from its initial position, one action is completed (from open to closed, or from closed to open), and conversely, the other action (from closed to open, or from open to closed) is completed.
