Double Block & Bleed Plug Valve
FlowBiz Double Block Bleed Plug Valves are designed following essential international standards. They also meet the requirements of significant hydrocarbon industry standards and customer specifications.
FlowBiz expanding plug valves are ideal for applications requiring positive shutoff, verifiable zero leakage, double block and bleed (DB&B), or double isolation and bleed (DIB) capability.
Range :
Size : 2 inch to 30 inch (50mm to 750mm) - 150 Class
Size : 2 inch to 24 inch (50mm to 600mm) - 300 Class
Size : 2 inch to 12 inch (50mm to 300mm) - 600 Class
Applications :
Blending Units :
The FlowBiz Double Block & Bleed Valves are designed for the perfect blending of ethanol. Other geographical fuel grades need valves with exceptionally high seal probity to guarantee precise measurement of additives and blending stocks
Product Isolation:
The FlowBiz Double Block & Bleed Valves are designed for reliable isolation of biofuels or other process-sensitivefluids critical for environmental and process safety. The FlowBiz DB&B’s provable zero leakage and positive shutoff abilities make it an ideal solution for process-sensitive applications and isolation.
Multi-Product Manifolds :
The FlowBiz Double Block & Bleed Valves are designed for refinery, pipeline, and transfer manifolds to flow multiple products (e.g. blending stocks, diesel, gasoline, jet fuel etc. reliably and without contamination. FlowBiz DB&B is a valuable tool for preventing cross-contamination of products.
Prover Loops :
For every valve in the prover loop system to have a zero leak rate, flow meters must have proper calibration — any error in calibration results in a leak. FlowBiz DB&B valves are used to ensure accurate calibration & leak-tight closure.
Custody Transfer Units :
Accurate measurement of product transfer quantity depends on the transfer of valuable media. The FlowBiz DB & B provides zero leak rate and positive shutoff, guaranteeing the accuracy of the transfer quantity calculation.
Offshore Platform :
Any leakage on an offshore platform results in facilities and environment loss. The FlowBiz DB & B has excellent low-pressure positive shutoff characteristics and is perfect for offshore platforms.
Terminals :
Terminals used for unloading and loading tankers require valves with positive sealing to prevent environmental damage due to spillage. The FlowBiz DB & B provides zero leak rate and positive sealing in a secure and one go valve solution.
Tank Farms (Oil Depots) :
Frequently operated Tank isolation valves have high reliability and require zero leak rate. The FlowBiz DB & B valve provides a high integrity seal designed and reliable for an instant, long-term and frequent use.
Aviation Fueling Systems :
Airport fueling systems require valves that close instantly and have provable seal integrity, allowing for quick maintenance, repair, leak location and testing -- the FlowBiz DB & B valve’s sustainable zero leak rate.
