Working Principle:
The disc of the German KSB BOAX-B T2 3G6K3GK Pneumatic Butterfly Valve is installed along the diameter direction of the pipeline. Within the cylindrical channel of the valve body, the disc-shaped butterfly plate rotates around the axis. The initial position of the valve is set according to 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 the reverse completes the other action (from closed to open, or from open to closed).
