Understanding DBB Ball ValvesDBB ball valves are designed to provide two independent seals (double block) and a bleed function to vent trapped pressure between the seals. This design ensures that the valve can safely isolate sections of the pipeline, preventing cross-contamination and facilitating m

Understanding Double Block and Bleed (DBB) Ball ValvesDBB ball valves are designed to provide two independent blockages and a bleed path to ensure complete isolation and venting of the fluid. This design is particularly useful in applications where maintenance or repairs are required, as it allows f
