What Are DBB Valves? ICCL’s Engineering for Safer Fluid Control

In industries that are critical to our daily lives, like oil and gas, petrochemicals, power generation, and marine operations, ensuring safety and preventing leaks is absolutely essential. A key player in maintaining process integrity and safety during maintenance is the DBB valve, which stands for Double Block and Bleed valve.

As a top-notch manufacturer of instrumentation valves in India, ICCL (Instrumentation Controls Co. Ltd.) provides high-performance DBB valves that adhere to rigorous safety, pressure, and material standards. With a commitment to precision engineering and zero-leak technology, ICCL has earned the trust of clients worldwide for their instrumentation, isolation, and pressure control solutions.

In this blog, we’ll take a closer look at DBB valves — what they are, how they function, and what makes ICCL’s designs a cut above the rest in the industry.

🧠 What Is a DBB Valve?

A Double Block and Bleed (DBB) valve is a unique valve assembly crafted to isolate a section of pipeline or equipment from both ends (double block) while also allowing for the venting or draining of any trapped fluid or pressure (bleed) in between.

Instead of relying on multiple valves and fittings, a DBB valve cleverly combines all three functions — block, block, and bleed — into one compact unit.
