Double Block and Bleed (DBB) Valves provide double isolation through two obturators integrated into a single body. They offer a bleed function via a bleed/vent system positioned between the obturators (body port and ball, gate, or needle valve), designed with a floating ball valve structure. DBB ball valves enable the isolation of a pipe section from both sides of the valve, enhancing safety by preventing accidental leaks that could cause harm. This design is especially beneficial in the oil and gas industry, ensuring secure operations. Additionally, the integrated design reduces the need for extra valves, optimizing both space and cost efficiency.
