Traditional isolation assemblies cost more than they should.
Conventional Double Block & Bleed setups with separate blind flanges introduce complexity, risk, and cost at every stage — from specification to maintenance.
Traditional Approach
DBB + Gate Valve + Blind Flange Assembly
- Multiple separate components: gate valve, block valve, spectacle blind
- Hours or days required to achieve positive isolation
- Operator exposure to process media during maintenance
- Pressure-energized seals wear over time — leak risk increases
- Complex logistics: specify, procure, and track multiple parts
- Higher total installed cost and extended commissioning time
BridgeFlow Model "Y" TMMBV
Single Integrated Isolation Valve
- Single integrated valve body replaces entire assembly
- Blind-flange-equivalent isolation achieved in seconds
- Zero operator exposure — mechanical isolation without line entry
- Bidirectional forced seal — integrity independent of pressure
- One valve to specify, purchase, and track
- Up to 50% fewer parts, reduced footprint, lower lifecycle cost

"BridgeFlow's Mechanized Ball Valve revolutionizes valve technology by offering unmatched durability, superior sealing, and environmental sustainability."

Each pillar addresses a real operational challenge — backed by patented technology, international standards compliance, and field-proven performance.

Zero
Line entry required for isolation
Pillar 01
Enhanced Safety
Eliminate exposure. Eliminate error.
The integrated design removes the need for operators to enter the line during isolation. Mechanical positive isolation is achieved without specialized tools — reducing human error and field exposure to process media.
- Meets OSHA 'blanking or blinding' definition for hazardous energy isolation
- No operator exposure during isolation or maintenance
- Consistent, repeatable mechanical seal — not pressure-dependent
- Reduces isolation procedure complexity for field teams

50%
Fewer parts in typical tie-ins
Pillar 02
Reduced Footprint
One valve. The entire assembly.
BridgeFlow replaces a multi-component assembly — gate valve, block valve, spectacle blind, and associated flanges — with a single compact body. Designed for space-constrained facilities and new-build efficiency.
- Up to 50% fewer components in typical tie-in configurations
- Single valve to specify, procure, and track
- Eliminates redundant sealing surfaces and leak paths
- Compact form factor suited for offshore and space-critical sites

TCO
Optimized across full asset lifecycle
Pillar 03
Lower Total Cost
Fewer parts. Less downtime. Longer life.
Extended service life, reduced maintenance frequency, and simplified logistics combine to deliver a lower total cost of ownership over the asset lifecycle. The friction-free switching mechanism eliminates wear on sealing surfaces.
- Friction-free ball rotation eliminates seal wear — extends service life
- Reduced installation time and commissioning labor
- Single procurement item simplifies supply chain
- Minimized downtime vs. traditional spectacle blind changeouts
