Double Block & Bleed Ball Valve
45 products found
A double block and bleed (DBB) ball valve integrates two independent seating surfaces and a central bleed mechanism into a single, space-saving body to replace bulky multi-valve manifolds. It simultaneously blocks fluid or gas pressure from both upstream and downstream directions using dual ball elements, while the localized intervening cavity can be safely drained or vented through a small bleed valve. This configuration allows technicians to verify absolute seal integrity and safely isolate downstream lines for maintenance without interrupting upstream line operations. By delivering redundant leak protection and a reduced structural footprint, this high-integrity valve is vital for custody transfer metering systems, chemical dosing lines, and high-pressure oil and gas manifolds. Global sourcing teams can partner directly with vetted DBB ball valve manufacturers in China through our streamlined commercial channel to secure heavy-duty, certified double block and bleed ball valves shipped straight from the factory.
