‌Pneumatic Three-Piece Ball Valve‌ is a ball valve driven by a pneumatic actuator, primarily used in industrial pipeline systems for controlling fluid flow and regulating flow rate. Its basic structure consists of a ball, valve seat, valve stem, and pneumatic actuator, with the ball rotating 90 degrees around the centerline of the valve body to achieve opening and closing.

Operating Principle

The working principle of the pneumatic three-piece ball valve is that it uses a pneumatic actuator to provide power, rotating the ball 90 degrees to complete the opening and closing action. Upon receiving an open signal, the ball rotates 90 degrees to open the passage; upon receiving a close signal, the ball rotates another 90 degrees to close the passage.

Structural Features

‌Compact Structure: The pneumatic three-piece ball valve consists of three valve bodies, featuring a compact structure, small size, and light weight.‌

‌Simple Operation: The switch operation is completed with a 90-degree rotation of the pneumatic actuator, featuring low torque for easy long-distance control._

‌Excellent sealing: The ball valve's sealing surface is widely made of plastics and other sealing materials, ensuring good sealing properties suitable for various media.‌

‌Maintenance Friendly: The design of the valve body and ball makes maintenance and replacement of the sealing rings relatively convenient._

Wide Application Range: Suitable for various mediums such as water, solvents, acids, and natural gas, particularly for harsh working conditions like oxygen and hydrogen peroxide.

Application Fields

Pneumatic three-piece ball valves are widely used in various fields such as petrochemical, chemical, power, environmental protection, water conservancy, heating, and water supply and drainage. Their excellent fluid control performance and reliable sealing properties play a crucial role in these applications.
