Floating Ball Valves DBB Flanged

The Oliver Twinsafe Floating Ball Double Block and Bleed (DBB) valves with 2- or 3-piece bolted construction are engineered for maximum efficiency, reliability, and safety within compact dimensions. This modular design incorporates conventional through-bolted flanged ends with optional hub or welded connections, enabling installation without costly pipework modifications. With overall lengths in accordance with ASME B16.10 (Class 600 and above), these valves can directly replace standard single isolate valves while providing the enhanced safety of true double isolation. The floating ball mechanism delivers robust sealing performance while minimizing weight and footprint, supporting pressure classes up to ASME 2500. Additionally, the full through bore complies with API 6D requirements, maximizing flow rates, maintaining production efficiency, and allowing for pipeline pigging operations. For more information, contact us at 02-168-3193-5, Hotline: 091-187-1111 or Line ID: @multiphase

Floating Ball Valves DBB Flanged 2/3 Piece Design

Our Flanged Style Double Block & Bleed Valves are available in both two and three piece body designs and contain three valves in one single unit – thus reducing weight and saving space across the installation. The two piece design is available in Oliver standard lengths up to ASME Class 300 and in accordance with ASME B16.10 lengths for ASME Class 600 and above. For the three piece design, all valves are have Oliver shortest overall length. Various other bleed valve options are available and we can work with our customers to adopt a technical project focused approach to ensure complete compatibility.
