Electric Actuated Metal-Seated Trunnion-Mounted Forged Ball Valve Supplier in South Africa

Severe-service applications require valves that can withstand high pressure, elevated temperatures, and abrasive media while maintaining reliable shut-off. African Valve supplies Electric Actuated Metal-Seated Trunnion-Mounted Forged Ball Valves for projects across South Africa where automated operation and long service life are essential. These valves are widely used in oil & gas, petrochemical, chemical processing, power generation, mining, marine, water treatment, pulp & paper, and steel industries.

Why Use an Electric Actuated Metal-Seated Trunnion-Mounted Forged Ball Valve?

• Designed for high-pressure and high-temperature applications.

• Forged body construction provides superior mechanical strength.

• Trunnion-mounted design reduces operating torque.

• Metal seats offer excellent resistance to erosion and abrasive media.

• Electric actuator enables remote and automated operation.

• Suitable for on-off and modulating service.

• Compatible with PLC, DCS, and SCADA systems.

• Ideal for critical isolation and emergency shutdown applications.

How Does It Work?

The trunnion-supported ball remains fixed while spring-loaded metal seats provide sealing. An electric actuator rotates the ball through 90° to control flow. Intelligent actuators provide accurate positioning and feedback signals for integration with plant automation systems.
