Our compact style Double Block & Bleed Valves are designed with an overall length in accordance with ASME B16:10. The single piece body design reduces potential leak paths and allows weight and space to be kept to a minimum. Available with both full and reduced bore sizes.
Oliver Twinsafe offers a range of valves in either full or reduced bore sizes, in ASME pressure classes from 150 to 2500 and API 6A ratings up to 10,000 psi. Both soft and metal seated options are available. These DBB valves are designed to offer one valve solution, available in most sizes to fit in the same space as a single ball valve (ASME B16.10 overall length) or with the shortest possible face to face dimension, giving true double isolation for maximum safety and reducing process problems due to valve leakage. The compact design saves weight, space and reduces costly installation charges.
