Design

The BridgeFlow Model “Y” Trunnion Mounted Mechanized Ball Valve is built upon a revolutionary non-intrusive blinding concept, redefining how pipeline isolation is performed. 

Traditional blind flange operations are like open surgery: requiring large-scale disassembly, exposing operators to hazardous media, demanding substantial workspace, depressurization, and costly medium displacement procedures—all while placing personnel directly in harm’s way.

Bridgeflow introduces a “minimally invasive” approach to pipeline isolation. Through a protected, pressure-contained valve body, a pair of solid sealing plates—equivalent to blind flanges—are mechanically engaged or disengaged via a single operating shaft. 

This enables true blind-level isolation within seconds, without exposing workers to any process medium or pressure risks.

Our patented design integrates all three isolation tiers in a single solution:

- Positive Isolation (Blind-Level): Safely replaces traditional blind flanges inside a sealed housing

- Double Block and Bleed (DBB): Seamlessly compatible with dual-valve isolation requirements

- Single Valve Isolation: Functions as a reliable single barrier where required.

The design of the BridgeFlow Model “Y” Trunnion Mounted Mechanized Ball Valve was driven by the goal of creating an environmentally friendly valve that provides value to customers.

Key design concepts include:

• Providing a mechanically sealing full port valve with unrestricted flow to minimize pressure drop and save energy when the valve is open.
• Incorporating verification of positive sealing in a bi-directional pressure envelope to prevent internal leakage and protect operators and the environment.
• Offering a non-rising stem, compact design with superior stem sealing technology to prevent external emissions and protect the environment.
• Providing a dematerialized design that is lighter and smaller than other mechanical sealing valves, reducing material use and environmental impact.
• Meeting major industry codes and standards, including API, ASME, and NACE/ISO, to maintain a leading position in the valve industry.
• Reducing operating torque to save energy during valve operation.
• Accepting manual, pneumatic, or electric operators with lower energy consumption and improved efficiency, saving energy and reducing costs for customers.
