Trunnion Ball Valves Industrial Equipment

3-Piece Forged Steel Trunnion Mounted Ball Valve

Engineered for Performance, Built for Reliability

The SET Valves 3-piece forged steel trunnion mounted ball valve is engineered for pipeline and critical service applications across the global energy infrastructure where zero-leakage, positive shutoff is required. With API monogram certification and full compliance with international standards, these valves deliver reliability, durability, and ease of integration into any piping network.

South East Texas Valves & Automation (SET Valves)

Our trunnion ball valves feature advanced engineering for exceptional performance in high-pressure and critical applications across the global energy infrastructure.

High Pressure Rating

Designed to handle extreme pressures up to 2500# with superior structural integrity and reliability.

Zero Leakage

Advanced sealing technology ensures bubble-tight shutoff even under the most demanding operating conditions.

Low Torque Operation

Trunnion mounting reduces operating torque, making actuation easier and extending actuator life.

Fire Safe Design

Built with fire-safe features and materials to maintain integrity even in extreme fire conditions.

Full Bore Design

Full bore construction minimizes pressure drop and allows for pigging operations in pipeline applications.

Easy Maintenance

Modular design allows for easy maintenance and repair without removing the valve from the pipeline.

Design Specifications & Compliance

Built to meet the highest international standards and certifications for critical service applications.
