Pneumatic clamping butterfly valve with pneumatic actuators. Pneumatic actuators's implementation speed is relatively fast, and workers do not need to do it themselves, which saves human resources and time to a great extent. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the initial position of the valve depends on the actual demand. When the valve rotates 90 degrees from the initial position, it is the end of one action (from opening to closing, or from closing to opening), and vice versa, it is the end of another action (from closing to opening, or from opening to closing).
