Pneumatic Actuated Ball Valve
Comprehensive range of pneumatic actuated ball valve for industrial applications across Angola
African Valve, a Pneumatic Actuated Ball Valve Supplier Angola, provides pneumatic actuated ball valves that combine the quarter-turn operation of a ball valve with compressed-air actuation. These valves provide fast opening and closing and can be integrated with PLC, DCS and SCADA systems for remote operation.

Pneumatic Actuation
The pneumatic actuator uses compressed air to turn the ball through 90°. In a double-acting actuator, air is used for both opening and closing. In a spring-return actuator, air moves the valve in one direction while spring force returns it to the required fail position.
