What is a lug style butterfly valve?
A lug style butterfly valve is a type of flow control device used to regulate the flow of liquids and gases in industrial settings. It has a disc-shaped closure element, usually made from metal or plastic, that is attached to the end of a lug (a short arm or handle). When the valve is opened, the disk opens perpendicular to its axis, allowing fluid to pass through.
Lug style butterfly valves are generally constructed from stainless steel that has been treated with an anti-corrosion coating for maximum durability. They come in many sizes and configurations depending on usage requirements such as pressure ratings and chemical compatibility. The most common types include wafer and double flanged versions, though others variations are also available. Depending on the application they can be automated using pneumatic or electric actuation mechanisms
What is the difference between lug type and double flange?
The difference between lug type and double flange valves lies in the construction of the valve. Lug type valves have two lugs on either side that fit into lugs in the pipeline, while double flange valves have a protruding flange around the circumference of the valve body. This allows for secure attachment when compared to lug type valves, which rely on bolts to attach them to other components. Double flanges are also better suited for pressurized systems as they provide more rigidity than lug type connections and can handle higher pressures with fewer maintenance issues.
What is semi lugged butterfly valve?
A semi-lugged butterfly valve is a type of valve used to regulate, stop, or start the flow of media in pipelines. It is composed of two disc-shaped components that create an opening or closing for the media to pass through. The disc is attached to a stem via lugs; hence its name “semi lugged butterfly valve”.
