These valves provide two independent sealing barriers with an integrated bleed function, allowing safe verification of isolation and controlled release of trapped pressure.

Valvenex supplies high-integrity DBB (Double Block and Bleed) ball valves designed for critical isolation and pressure control in demanding industrial environments.
DBB ball valves are widely used in oil & gas, petrochemical, LNG, and power generation applications where safety, reliability, and operational efficiency are essential. By integrating multiple functions into a single valve solution, they help reduce system complexity, minimize leak paths, and lower installation and maintenance costs.
Our DBB ball valves are available in floating and trunnion-mounted designs, engineered to handle high-pressure systems, aggressive media, and extreme operating conditions. Manufactured in compliance with international standards such as API, ASME, and ISO, they ensure consistent performance and full traceability across projects.
The double block function isolates the process from both upstream and downstream pressure, while the bleed feature enables safe cavity pressure release or leak testing between the seals. This makes DBB valves ideal for applications requiring zero leakage, maintenance safety, and system integrity verification.
At Valvenex, we support more than just supply. Our engineering team works closely with clients to ensure correct valve selection based on process requirements, pressure ratings, materials, and actuation needs. We also assist with certification, documentation, and compliance to meet project-specific standards.
With a strong focus on safety, performance, and reliability, Valvenex DBB ball valves are trusted by operators and contractors worldwide for critical service applications.
