Connection Lift Plug Valve

A connection lift plug valve lifts the plug away from its seating surface before rotation, reducing rubbing between the plug and seat during operation. Connection Lift Plug Valve Suppliers in Algeria can provide this design for process and pipeline isolation where reduced seating wear, lower operating friction and dependable shut-off are required. African Valve supplies connection lift plug valve configurations for industrial applications.

Key Features

• Lift-to-Unseat Operation: The plug lifts away from the seat before rotating.

• Reduced Seat Wear: Minimises sliding contact during opening and closing.

• Lower Operating Friction: Reduces resistance during plug movement.

• Reliable Isolation: Provides positive on/off flow isolation.

• Full / Reduced Port: Available according to flow requirements.

• Manual / Actuated: Can be operated manually or with suitable actuation.
