Lug Type Butterfly Valve Operating Mechanism: 

Lug Type Butterfly Valve is characterized by threaded lugs that enable each of the flanges on the pipelines to be bolted individually to the body of the valve. Such an arrangement allows one side of the pipeline to be opened without shutting down the other side, making this type of valve ideal for use in dead ends and maintenance applications.

The quarter-turn disc arrangement makes such valves easy and quick to open and close using little operating force.
