Pneumatic Metal Seat Flanged Ball Valve Supplier in South Africa

High-temperature and abrasive services demand valves that can maintain sealing performance under severe operating conditions. African Valve supplies Pneumatic Metal Seat Flanged Ball Valves for projects across South Africa where automated operation and wear resistance are critical. These valves are widely used in oil & gas, petrochemical, power generation, mining, chemical processing, marine, pulp & paper, and steel industries.

Why Use a Pneumatic Metal Seat Flanged Ball Valve?

• Suitable for high-temperature and severe-service applications.

• Metal seats provide excellent resistance to erosion and abrasion.

• Flanged design simplifies installation and maintenance.

• Pneumatic actuation enables quick remote operation.

• Delivers reliable shut-off under demanding conditions.

• Suitable for slurry, steam, and abrasive media.

• Available for on-off and modulating service.

• Designed for long service life and reduced maintenance.

How Does It Work?

The valve uses a precision-machined ball and hard-faced metal seats to control flow. A pneumatic actuator rotates the ball through 90° using compressed air. When the ball port aligns with the pipeline, media flows freely. Rotating the ball perpendicular to the flow path isolates the line. Double-acting and spring-return actuators are available depending on system requirements.
