Lug-style butterfly valves feature threaded lugs on both sides of the body, allowing connection with two separate sets of bolts\u2014one for each flange\u2014without the need for nuts. This design enables the valve to maintain its connection even if one side of the piping system is disconnected, keeping the other side undisturbed. Made from metals like steel or ductile iron, these valves are ideal for end-of-line service, often paired with a blind flange for maintenance.<\/p>

While versatile and resistant to chemicals, lug-style butterfly valves have a lower pressure rating in dead-end services. For example, a valve mounted between two flanges can handle 1000 kPa, but on a single flange, the rating drops to 520 kPa. They can also withstand temperatures up to 200\u00b0C, allowing for easy cleaning, inspection, replacement, or repair without shutting down the entire system.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
