Custom Pneumatic Butterfly Valve Suppliers, Factory, Manufacturing Company

The pneumatic butterfly valve adopts a wafer-type design with a compact structure, small size, and lightweight design, making it convenient to install, transport, and maintain. It is driven by a pneumatic actuator that rotates the valve stem, enabling the disc to rotate quickly within the valve body by 90°, achieving rapid opening and closing with fast response. It precisely controls flow according to system requirements, providing stable and reliable throttling, cutoff, and isolation functions. The valve uses elastic sealing materials such as rubber or PTFE to ensure effective leakage prevention when closed. The pneumatic butterfly valve is suitable for various media such as water, oil, and steam and operates within a wide range of pressures and temperatures, meeting the demands of different piping systems.
