Double Block and Bleed (DBB) Valves provide a reliable double isolation function using two obturators housed within a single body. The bleed function is achieved via a bleed/vent system positioned between the obturators, which can be configured as a body port and ball, gate, or needle valve. Derived from the floating ball valve design, KOSEN DBB valves are available in several construction types to suit different applications. Double block and bleed ball valves allow a pipe section to be isolated from both upstream and downstream sides, ensuring enhanced safety by preventing accidental leaks that could cause harm. In addition to their robust safety features, these valves reduce the need for multiple valves in a pipeline, saving space, minimizing installation complexity, and lowering overall costs. They are particularly efficient and widely used in the oil and gas industry.
