Double Block and Bleed Valves provide double isolation through two shut-off elements housed within a single body. They also offer a bleed function via a bleed/vent system situated between the shut-off elements (body port and ball, gate, or needle valve). Derived from the trunnion ball valve design, DBB valves come in various constructions. These valves enable a pipe section to be isolated from both sides, preventing accidental leaks and enhancing safety, which is crucial in the oil and gas industry. Additionally, they minimize the need for extra valves, thus saving space and reducing costs.
