    Tips: Why choose our pneumatic butterfly valve?

    • Pneumatic PVC butterfly valve has the advantages of simple structure, small size, light weight, low consumables, small installation size, and small 90° reciprocating rotation driving torque. It is used to cut, open and adjust the medium in the pipeline, and has good flow control and sealing performance.
    • Our air driven butterfly valve can not only transport air, water and oil, but also mud, leaving little liquid at the pipe mouth. Good sealing and good regulation are achieved at low pressures.
    • The butterfly disc is designed for streamline, and the loss of fluid resistance is small. Pneumatic butterfly valve can be said to be an energy-saving product.
    • The valve stem of the pneumatic butterfly valve is a through-rod structure, which has good comprehensive mechanical properties, corrosion resistance and wear resistance. When the pneumatic butterfly valve is opened and closed, the valve stem only rotates and does not move up and down, and the sealing is reliable.
    • The connection methods of pneumatic butterfly valve include flange connection, wafer connection and lug connection. The valve body material is PVC, stainless steel, cast iron. The air butterfly valve is driven by a pneumatic actuator, which can realize remote control and automatic operation.
