Lubricated Plug Valve

Lubricated plug valves use an injectable sealant system to maintain sealing between the plug and body while reducing friction during operation. African Valve is a prominent lubricated plug valve suppliers in Nigeria configurations for pipeline and process services where dependable isolation and maintainable sealing performance are required.

Key Features

• Sealant Injection: Injects lubricant or sealant into the plug sealing areas.

• Reduced Operating Friction: Lubrication assists plug movement.

• Reliable Isolation: Provides quarter-turn shut-off.

• Sealant Replenishment: Sealing performance can be maintained through injection.

• Metal Seating: Suitable for demanding hydrocarbon and process services.

• Manual / Actuated: Available with wrench, gearbox or actuator operation.
