Pneumatic flange three-way ball valve
The Pneumatic Flange Three-Way Ball Valve is an automated multi-port valve designed for efficient flow switching, distribution, and mixing applications. Equipped with a pneumatic actuator, the valve provides fast response, reliable operation, and easy integration into industrial automation systems.
The three-way ball design allows flexible control of fluid flow through different flow patterns, including L-port and T-port configurations, enabling functions such as flow diversion, mixing, and shut-off. The flanged connection design ensures secure installation, excellent sealing performance, and convenient maintenance.
With a compact structure, low operating torque, high flow capacity, and reliable sealing performance, the Pneumatic Flange Three-Way Ball Valve is widely used in industries requiring precise flow control and automatic operation, including chemical processing, oil & gas, water treatment, power generation, and industrial pipeline systems.
