The DPE × SPE DIB-1 / DIB-2 Trunnion Ball Valve with Support Plate Structure is designed for high-integrity pipeline isolation in applications that require clearly defined seat-sealing behavior and controlled cavity pressure management.
A rigid support plate structure anchors the ball and bearing system, helping limit ball deflection under high pipeline thrust. This arrangement is especially useful for the listed 24-inch size, where structural stability and even seat loading are important for reliable operation.
The valve supports different SPE and DPE seat combinations. In a DIB-1 arrangement, two DPE seats provide bidirectional sealing barriers. In a DIB-2 arrangement, one SPE seat and one DPE seat combine double isolation with a defined cavity-pressure-relief path.
The current product configuration uses LF2 low-temperature carbon steel, DEVLON soft seats, Class 300 rating and API 6D design. Split-body construction, fire-safe features and optional sealant injection further support maintenance and critical pipeline service.

Rigid Support Plate: Heavy-duty support plates hold the ball and bearings in position, helping reduce ball deflection and uneven seat loading in large-bore service.
DIB-1 Configuration: Two DPE seats provide two bidirectional sealing barriers for applications requiring double isolation from either pipeline direction.
DIB-2 Configuration: One SPE seat and one DPE seat combine double isolation with a defined self-relieving cavity-pressure path.
Safety & Maintenance: Anti-static design, an anti-blowout stem, fire-safe construction and optional emergency sealant injection support critical isolation duties.

The DIB-1 / DIB-2 Support Plate Trunnion Ball Valve is suited to critical pipeline nodes where verified isolation, pressure management and structural stability are important.
Custody Transfer Metering Skids: Provides positive isolation around metering equipment to help limit unintended bypass during measurement and maintenance.
Product Manifolds: Supports separation of different process streams and controlled routing in complex oil, gas and liquid-transfer networks.
Pig Launcher & Receiver Stations: DIB seat configurations provide defined isolation barriers and cavity-pressure management during pigging preparation and maintenance.
High-Integrity Pipeline Isolation: The support plate and configurable SPE/DPE seats are suitable for large-bore pipeline sections that require robust mechanical support and planned isolation logic.
