Electric Actuated Trunnion-Mounted Casting Ball Valve Supplier in Nigeria

Automated pipeline systems require valves that provide reliable shut-off, low operating torque, and long service life. African Valve supplies Electric Actuated Trunnion-Mounted Casting Ball Valves for projects across Nigeria where remote operation and dependable sealing are essential. These valves are widely used in oil & gas, petrochemical, chemical processing, power generation, mining, marine, water treatment, and steel industries.

Why Use an Electric Actuated Trunnion-Mounted Casting Ball Valve?

• Trunnion-mounted design reduces operating torque.

• Cast body construction offers excellent strength and durability.

• Electric actuator enables remote and automated operation.

• Suitable for large-diameter and high-pressure pipelines.

• Provides reliable shut-off with reduced seat wear.

• Available for on-off and modulating service.

• Compatible with PLC, DCS, and SCADA systems.

• Designed for critical isolation applications.

How Does It Work?

The ball is supported by upper and lower trunnions, which minimize stress during operation. An electric actuator rotates the ball through 90° to open or close the valve. Intelligent actuators provide accurate positioning and can transmit status feedback to control systems for automated process operation.
