Replace a single ball valve by a Double Block & Bleed

DBB - Safe solution couse valve meet the face-to-face requirements of ASME B16.10.

When creating the design specification for our Taurus Series we came along the point ‘face to face’ dimensions. Immediately some colleague said “ASME B16.10 and EN 558 – but same length as a single ball valves for the Taurus DBB with 2 balls and a bleed in between?”

Well, we discussed that there might be a possibility to achieve this goal and we listed some values and benefits we could offer to our customers with such a short face to face dimension:

The major benefit would be that the new Double Block & Bleed (DBB) Pipeline Ball Valve (Taurus-Series) has the same face-to-face dimension as a single block ball valve. The length of a single block ball valve is specified in ASME B16.10 and APl 6D. As a consequence the valve can easily be installed into an existing pipeline without the need for any re-work on the pipeline.
