Model "Y" TMMBV

Trunnion Mounted Mechanized Ball Valve

A patented, integrated isolation valve that combines friction-free ball rotation, extended service life, and one-stop isolation functionality — including DBB, DIB, and blind-flange-equivalent positive isolation — in a single compact body.

Operational Logic

How the BridgeFlow TMMBV works

A simplified technical walkthrough of each operational state — engineered for both field teams and commercial decision-makers.

Open Position

Friction-Free, Unrestricted Flow

When the valve is in the open position, the ball assembly retracts the segments and rotates until fully open. This creates a friction-free interface between the ball and the seats — eliminating wear during normal operation.

  • Ball segments retract fully to allow unrestricted flow
  • No contact between ball and seats during rotation — zero friction wear
  • Minimizes pressure drop across the valve body
  • Reduces energy consumption compared to traditional trunnion designs
  • Compatible with manual, pneumatic, or electric operators
Integrated Blind Flange Design

The end of line blind operations

The patented integrated blind flange design eliminates the need for line blind flanges entirely. The patented friction-free switching mechanism removes wear and tear, extending service life while delivering higher-level isolation than traditional Double Block and Bleed configurations.

This design meets the stringent requirements of OSHA's "blanking or blinding" definition for hazardous energy isolation — the most rigorous standard for positive isolation in industrial process systems.

Seconds, Not Days

Achieves blind-flange-equivalent positive isolation in seconds — vs. hours, days, or weeks with traditional blinding techniques.

No Specialized Manpower

No specialized tools or additional crew required. A single operator can achieve full positive isolation safely.

Zero Operator Exposure

Mechanical isolation eliminates the need for operators to enter the line or be exposed to process media during isolation.

Accelerated Commissioning

Faster tie-in and commissioning timelines — directly reducing project schedule risk and associated costs.

Fewer Components

Eliminates line blind flanges, reducing total part count by up to 50% in typical tie-in configurations.

Lower Lifecycle Cost

Fewer components, reduced maintenance needs, and simplified logistics deliver measurable total cost of ownership savings.
