Pneumatic Floating Ball Valve Suppliers in Nigeria

An automated isolation is essential in high-pressure pipelines and critical process systems. African Valve supplies Pneumatic actuated floating ball Valves for projects across Nigeria where low operating torque, dependable sealing, and remote operation are required. These valves are widely used in oil & gas, petrochemical, chemical processing, water treatment, power generation, mining, marine, and steel industries.

Why Use a Pneumatic Actuated Floating Ball Valve?

Cast body construction provides strength and durability.
Suitable for high-pressure and large-size pipelines.
Delivers tight shut-off with low seat wear.
Pneumatic actuation allows fast and reliable operation.
Suitable for automated and emergency shutdown systems.
Available in full bore and reduced bore configurations.
Designed for continuous industrial service.

How Does It Work?

The ball is supported by upper and lower trunnions, keeping it fixed under pressure. During operation, the seats move towards the ball to provide reliable sealing. A pneumatic actuator rotates the ball by 90° using compressed air, allowing quick opening and closing without manual effort. Double-acting and spring-return actuators are available depending on fail-safe requirements.
