FlowBiz: High-Performance Double Block & Bleed (DB&B) Plug Valves
The Gold Standard for Positive Shutoff and Zero Leakage
FlowBiz Export Private Limited is a premier manufacturer of Double Block & Bleed (DB&B) Plug Valves, specifically engineered for the most critical hydrocarbon and process industry applications. Our expanding plug valves are designed to exceed international standards, providing a verifiable zero-leakage solution where safety and precision are non-negotiable.
When your operations require Double Isolation and Bleed (DIB) or DB&B capabilities, FlowBiz provides a robust, single-valve solution that replaces traditional two-valve systems, saving space, reducing weight, and significantly lowering potential leak paths.
Engineering Excellence: How DB&B Plug Valves Work
The FlowBiz DB&B Valve utilizes an expanding plug mechanism. In the closed position, the slips are mechanically forced against the valve body, creating an upstream and downstream seal simultaneously. This allows the body cavity to be "bled" or vented to verify seal integrity, ensuring provable zero leakage.
Technical Range & Specifications
Our DB&B range is built to handle high-pressure environments across various industrial scales:
Pressure Class | Size Range (Inches) | Size Range (Metric) |
ASME Class 150 | 2 inch to 30 inch | 50mm to 750mm |
ASME Class 300 | 2 inch to 24 inch | 50mm to 600mm |
ASME Class 600 | 2 inch to 12 inch | 50mm to 300mm |
Key Industrial Applications
1. Blending Units & Product Isolation
FlowBiz DB&B valves are essential for the precise blending of ethanol and various fuel grades. High seal integrity guarantees that additives and blending stocks are measured accurately without cross-contamination. For process-sensitive fluids like biofuels, our valves provide a provable seal that ensures both environmental and process safety.
2. Multi-Product Manifolds & Prover Loops
In refineries and transfer manifolds, FlowBiz valves allow multiple products—such as diesel, gasoline, and jet fuel—to flow through the same system without risk of mixing. For Prover Loops, our valves ensure accurate flow meter calibration by providing a guaranteed leak-tight closure.
3. Custody Transfer & Terminal Loading
Accurate quantity calculation in custody transfer depends on zero leakage. FlowBiz ensures that every drop is accounted for. At marine terminals and tanker unloading stations, our valves prevent environmental damage by providing secure, one-go positive sealing.
4. Offshore Platforms & Tank Farms
On offshore rigs, where any leak results in environmental and financial loss, our valves offer excellent low-pressure positive shutoff. For Tank Farms (Oil Depots), our frequent-use design ensures long-term seal integrity even with constant operation.
5. Aviation Fueling Systems
Airport fueling requires instant closure and provable seal integrity for rapid maintenance and leak testing. FlowBiz DB&B valves provide a sustainable zero-leak rate that keeps aviation logistics moving safely.
