OurProductRange
Comprehensive valve solutions from DN 15 to DN 3000, with pressure ratings up to ASME Class 2500. Six product families engineered for the world's most critical industrial applications.
Ball Valve Solutions
ALLSEN's ball valve range covers three distinct designs, each optimized for specific service conditions. From high-pressure trunnion-mounted isolation to zero-leak fully welded installations, our ball valves deliver reliable quarter-turn operation across the full spectrum of industrial applications.
Trunnion Ball Valves
High-pressure pipeline isolation with double block and bleed (DBB) and double isolation and bleed (DIB) sealing configurations. Available in NPS 2 through NPS 56, pressure Class 150 to 2500. Designed for upstream and midstream oil & gas transmission where zero-leakage isolation is critical.
Floating Ball Valves
Available in 2-piece and 3-piece body configurations for process isolation service. Delivers bubble-tight shutoff through downstream seat sealing. Ideal for chemical processing, petrochemical plants, and general industrial applications where compact, reliable isolation is required.
Fully Welded Ball Valves
Zero-leak body design with no external bolting — purpose-built for direct burial and district energy systems. The fully welded construction eliminates potential leak paths, making these valves ideal for underground installations where maintenance access is limited or impossible.
Which industries rely on ALLSEN valves?
ALLSEN valves are trusted across eight critical industry sectors worldwide, delivering reliable performance where failure is not an option.
