Oliver Twinsafe Valves’ new range of Double Block and Bleed (DBB) large-bore pipeline valves offer a range of valves from 1″ ANSI class 150 to 12″ class 2500 with various face-to-face dimensions. Several advantages are claimed for using an Oliver Twinsafe DBB valve: all valve components housed in a single unit; replaces traditional DBB configurations; significant decrease in potential leak paths; offers a negligible pressure drop across the unit; pipelines can be pigged without any problems; saves time and money on costly installation and testing; offers complete solutions for DBB configurations.
