Why Use a Pneumatic Three Piece Ball Valve?

• Provides fast quarter-turn operation.

• Suitable for automated on-off applications.

• Three-piece construction allows easy maintenance without removing pipe ends.

• Full port design minimizes pressure drop.

• Offers bubble-tight shut-off for liquid and gas services.

• Supports frequent opening and closing cycles.

• Can be integrated with PLC and control systems.

How Does It Work?

A pneumatic actuator uses compressed air to rotate the ball through 90°. When the ball bore aligns with the pipeline, media flows freely. Rotating the ball perpendicular to the flow stops the passage and isolates the system. The actuator can be supplied in double-acting or spring-return configurations depending on fail-safe requirements.
