Pneumatic Trunnion Forged Metal Seat Ball Valve Supplier in Egypt

Severe-service pipelines require valves that can withstand high pressure, elevated temperatures, and abrasive media while maintaining reliable shut-off. African Valve supplies Pneumatic Trunnion Forged Metal Seat Ball Valves for projects across Egypt where automated operation and long service life are critical. These valves are widely used in oil & gas, petrochemical, mining, power generation, chemical processing, marine, and steel industries.

Why Use a Pneumatic Trunnion Forged Metal Seat Ball Valve?

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

• A trunnion-mounted ball reduces operating torque.

• Metal seats provide excellent resistance to erosion and wear.

• Forged body construction offers superior strength and pressure integrity.

• Suitable for abrasive and severe-service media.

• Pneumatic actuation enables fast remote operation.

• Available in double-acting and spring-return configurations.

• Suitable for emergency shutdown and automated isolation systems.

How Does It Work?

The trunnion-supported ball remains fixed while the seats move against the ball under pressure to achieve tight sealing. A pneumatic actuator rotates the ball through 90° using compressed air. When the bore aligns with the pipeline, flow passes freely. Rotating the ball perpendicular to the flow isolates the system quickly and efficiently.
