Double Block and Bleed (DBB) Valves provide double isolation by integrating two obturators within a single body, offering enhanced safety and performance. They feature a bleed/vent system located between the obturators (body port and ball, gate, or needle valve), which allows for safe venting of trapped fluids. Available in various trunnion ball valve designs, DBB valves come with multiple construction options.
Double Block and Bleed Ball Valves (DBB ball valves) enable a pipe section to be isolated from both sides of the valve, preventing accidental leaks and enhancing safety, particularly in the oil and gas industry. These valves not only ensure strong security but also reduce the need for additional valves, optimizing space and cost efficiency.
