High-performance Double Offset Butterfly Valves are designed for use in exceptionally harsh conditions with critical shutoff isolation and throttling control applications. The aptly named Colossus is available as a Metal Seated or PTFE seated design. The Colossus is one of our most reliable products because it's made from high-quality materials that can withstand the harshest conditions while still working reliably over long periods of time with minimal maintenance required. Lugged butterfly valves are a great choice for applications where you need to be able to disconnect the piping from either side of the valve. These lugged connect style butterfly valves feature a built in alignment guide through its bolt holes on both sides.
