Compact design provides 55% less weight and 60% of envelope size when compared to fabricated arrangement.Face-to-face length means no unnecessary change to existing installation when replacing a single isolation valve to ASME B16.10 length for class 600 and above.Single body joint means fewer potential leak paths and a safer, more practical arrangement.DBB assembly provides up to 65% installation time reduction against some traditional methods with fewer connections necessary.Provides security with double isolation barrier on process connection to valve outlet.
