It is very easy to upgrade your existing Single Isolate Ball Valve installation. By simply using a Double Block and Bleed (DBB) Valve with Face-to-Face and End-to-End dimensions acc. to ASME B16.10, which is a specification standardises those dimensions.

It is very easy to upgrade your existing Single Isolate Ball Valve installation. Simply use a DBB with Face-to-Face and End-to-End dimensions acc. to ASME B16.10.
Use a DBB Dual Ball Design improve Safety and Process Reliability. Here is a simple infographic to illustrate the interchangeability using ASME B16.10 dimensions:

Ever since 1922, ASME (American Society of Mechanical Engineers) has been defining pipeline safety upon demand from both industry and government. One of their standards has to do with face-to-face as well as end-to-end dimensions of straightway valves, centre-to-face and centre-to-end dimensions of angle valves. In this informative post, our primary focus will be on ASME B16.10 industrial valves.

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.
