The disc of the German KSB ACTAIR C12 F05+F07 DD14 pneumatic butterfly valve is installed along the diameter direction of the pipeline. Within the cylindrical channel of the butterfly valve body, the disc-shaped disc 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, another action is completed (from closed to open, or from open to closed).

Features of the German KSB ACTAIR C12 F05+F07 DD14 pneumatic butterfly valve:
Pneumatic wafer butterfly valves come in two sealing types: elastic sealing and metal sealing. For elastic sealing valves, the sealing ring can be embedded in the valve body or attached around the disc.
Pneumatic wafer butterfly valves have a long service life but are difficult to achieve complete sealing. Metal seals can adapt to higher working temperatures, while elastic seals have the limitation of being temperature-sensitive.
The clever wedge design enables the pneumatic wafer ball valve to have an automatic sealing function that tightens as it closes.
Pneumatic wafer butterfly valves have a simple structure, small size, and light weight, consisting of only a few components, making them easy to install.
When the pneumatic wafer butterfly valve is in the fully open position, the thickness of the disc is the only resistance to the medium flowing through the valve body. Therefore, the pressure drop generated by the valve is minimal, resulting in excellent flow control characteristics.
