Through specialized material and seal selection, optimized bonnet design, and precision machining of sealing surfaces, our Trunnion-Mounted and Floating Ball valves reliably operate down to -296°C. The products have passed numerous authoritative certifications and long-term verification. Our dedicated assembly and testing center is capable of performing full-range tests including leak detection and torque verification. For sour service applications, vent and drain connections adopt pad flanges complete with blind flanges, eliminating potential leak risks at threaded joints.
