DBB Pipeline Ball Valves

Modular Double Block and Bleed (DBB) valves from Oliver Twinsafe are engineered to deliver a true one-valve solution by integrating multiple isolation functions into a single compact unit. With face-to-face dimensions equivalent to a standard single ball valve—or the shortest possible in the industry—these valves can be installed without modification to existing pipework, significantly reducing space and weight. Despite their compact footprint, they deliver genuine double isolation, ensuring maximum safety, leak prevention, and process integrity in critical applications. The Oliver Twinsafe DBB design delivers exceptional advantages, including substantial space and weight savings—often exceeding 50% compared to traditional dual-valve configurations with spool pieces. By eliminating multiple separate valve assemblies, the number of leak paths is dramatically reduced, enhancing system safety and reliability. In addition, fewer components result in lower purchasing costs, simplified logistics, and reduced installation and maintenance expenses, providing a superior life-cycle cost benefit for operators across demanding industries.
