Browse our precision-engineered Double Block & Bleed valves, designed for critical isolation and maintenance in high-pressure or hazardous systems. Available in carbon steel, stainless steel, and high-pressure formats.
At ISIS Fluid Control, our Double Block & Bleed (DBB) valves are manufactured to provide maximum isolation, venting, and safety in demanding applications. These valves are ideal for maintenance or system intervention, ensuring two in-line block valves and a bleed valve operate within a compact, single unit to reduce potential leak paths.
Commonly used in oil and gas, petrochemical, chemical processing, and energy industries, DBB valves ensure safe and leak-free shutdown during instrumentation or pipeline servicing. Their compact and efficient design replaces complex multi-valve assemblies, saving space and installation time.
We offer a diverse selection of DBB valves including:
Carbon Steel Double Block & Bleed – Suitable for general industrial applications where robust construction and cost-efficiency are key.
High Pressure Double Block & Bleed – Engineered to handle extreme pressures and high-integrity applications with dependable performance.
Stainless Steel Double Block & Bleed – Corrosion-resistant and ideal for offshore, chemical, and aggressive media environments.
