There is a lot of misunderstanding surrounding the term double block-and-bleed (DBB) as used to describe valve functionality. It seems almost every valve buyer and manufacturer has a different idea of what the term means for valve selection, which can result in the wrong specifications or valve type. Some of this confusion in the oil and gas industry stems from the fact that there are two credible sources that define the term differently.
Double Block & Bleed valves provide true double positive isolation. This configuration provides the best technology for the most severe isolation services where double block and bleed is required. These valves are designed to ASME B16.34 and ideal for major oil refineries where safety and reliability are critical.
