5500 Double Block & Bleed Ball Valve
Brand: Cameron
The term Double Block-and-Bleed (DBB) has been an ongoing debate in the oil and gas industry, mainly because there are two credible sources that define the term differently. Basically, the difference is that API allows DBB to be one single valve with two unidirectional seats, while OSHA requires a DBB valve to be two individual valves in the same unit. In one compact design, the TBV Series 5500 double block-and-bleed (dbb) ball valve provides the two individual isolation valves required by OSHA. Features and Benefits:
