A single block and bleed (SBB) valve uses one block valve plus one bleed valve for isolation and pressure relief in one direction. A double block and bleed (DBB) valve uses two block valves plus one bleed valve for dual isolation from both directions, providing the dual seating required by API 6D in high-hazard applications. […]
