Products / Instrumentation Valves / Double Block & Bleed Valves

Double Block & Bleed (DBB) Valves are crucial for achieving verified process isolation. These compact units integrate two block valves and one bleed valve into a single body, ensuring a robust, secure isolation point. The first block valve isolates the line, the second provides a backup, and the central bleed valve safely releases trapped pressure. This essential configuration allows for safe maintenance and access to instrumentation (like pressure transmitters) without shutting down the main process line. Using HP Valves and Fittings India DBB valves significantly reduces potential leak paths, installation weight, and costs, greatly enhancing system safety and reliability in all high-pressure environments.
