Pneumatic soft-sealed wafer butterfly valve is a type of valve used for pipeline system opening and closing as well as flow control, widely used in the oil, chemical, metallurgy, hydropower, and other fields. Its design features include:

Structural Features: The butterfly plate of the pneumatic soft-sealed clamped butterfly valve is mounted in the diameter direction of the pipeline. The valve body is constructed with a short-distance clamped structure to accommodate the narrow pipeline space, featuring compact structure, light weight, and easy installation.

Sealing Materials: Typically featuring elastic sealing, these materials are usually made of soft substances like rubber or polytetrafluoroethylene, offering excellent sealing properties and corrosion resistance.

Operation Principle: The pneumatic soft-seated butterfly valve consists of a pneumatic actuator and a butterfly valve. The actuator is powered by compressed air, which drives the valve stem to rotate. This rotation then moves the disc-shaped butterfly plate to rotate within the pipeline, altering the cross-sectional area and flow rate of the pipeline, thereby controlling the fluid.
