DBB Valve

Home/Tags/Valve Types/DBB Valve

A DBB Valve, or Double Block and Bleed Valve, features dual seating surfaces to block fluid flow from both upstream and downstream sources. It incorporates a vent or bleed valve between the two block valves to release trapped pressure safely. Commonly used in safety-critical industries like oil and gas, chemical processing, and power generation, DBB valves ensure enhanced safety for personnel and equipment.
