Double Block and Bleed Ball Valve

A Double Block and Bleed Ball Valve, or DBB Ball Valve, incorporates two separate seals to create a double isolation barrier within a single valve body, offering a central vent or bleed port for pressure relief and maintenance purposes. The Valve is utilized to ensure safety, prevent cross-contamination, and maintain the integrity of fluid systems.
