API 6D DBB Ball Valve

The API 6D Double Block and Bleed (DBB) Ball Valve is a high-performance valve engineered to provide superior isolation, pressure control, and operational reliability in critical pipeline systems. Widely used in oil & gas, petrochemical, and high-pressure pipeline applications, these valves ensure safe and efficient system operation by preventing leakage, isolating sections for maintenance, and managing pressure safely.

An API 6D DBB ball valve features a dual-seat design within a single valve body, providing two independent ball seats for double isolation. Positioned between the seats is a bleed or vent valve, allowing controlled pressure release to enhance safety and reduce the risk of overpressure incidents. This configuration ensures bi-directional shutoff, compact design, and minimal leakage, meeting the strict requirements of API 6D standards. Many models also incorporate fire-safe designs and sealant injection ports to enhance reliability and meet rigorous safety and environmental compliance standards.

Sizes and pressure ratings vary to suit diverse pipeline requirements, from medium- to high-pressure applications, making API 6D DBB valves a critical component in pipeline integrity management. By combining dual isolation with a bleed function, these valves reduce maintenance downtime, enhance safety during operations, and provide operators with confidence in pipeline control.

In all cases where the Official API Monogram is applied, it is used in conjunction with API Certificate Number 609-0341, confirming compliance with API design, material, and testing requirements.
