The ASME Trunnion Subsea Ball Valve is a specialized, high-integrity valve designed for deep-water environments. It features a blowout-proof stem and a fixed-ball (trunnion) design to manage high pressures and extreme external depths. Engineered for durability, it utilizes corrosion-resistant materials and specialized seals to prevent seawater ingress. These valves are critical for subsea manifolds and pipelines where maintenance is difficult and zero-failure reliability is mandatory.
