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.

Oil & Gas Transmission
Pipeline isolation, metering stations, and compressor stations requiring trunnion ball valves with DBB/DIB sealing and full automation packages.
Petrochemical Processing
Process isolation and control across refineries and chemical plants, demanding corrosion-resistant materials and fire-safe certification.
Power Generation
Steam isolation, feedwater control, and cooling water systems in thermal and combined-cycle power plants.
District Energy
Fully welded ball valves for buried hot water and chilled water distribution networks serving urban heating and cooling systems.
Water & Wastewater
Butterfly and gate valves for treatment plants, pumping stations, and distribution networks handling potable and process water.
Mining & Slurry
Heavy-duty valves engineered to handle abrasive slurry media in mineral processing and tailings management.
Pulp & Paper
Process valves for chemical recovery, stock preparation, and steam systems in pulp and paper manufacturing facilities.
Marine & Offshore
Valves designed for offshore platforms, FPSOs, and marine vessels meeting the corrosion and safety demands of saltwater environments.
