Pneumatic operated butterfly valve has a basic structure, a compact size, and only a few components. There are two types of butterfly valve seals: soft seal and metal seal. The sealing ring can be integrated into the valve body or affixed to the butterfly plate's periphery. Metal-sealed valves generally have a longer life than soft-sealed valves, although achieving a full seal is challenging. The metal seal can adjust to a higher operating temperature, whereas the soft seal is temperature-limited. Wafer-type and flange-type butterfly valves are both frequently used pneumatic operated butterfly valves. The wafer type butterfly valve is used to link two pipe flanges together using stud bolts. Flange type butterfly valves feature a flange on the valve body, and bolts connect the valve's two ends to the pipe flange.
