Launches Next-Gen Hard Seal Super Hard Ball Valve for Extreme Service Applications

Conquering Extreme Conditions with Super Hard Sealing

The cornerstone of this new valve line is its revolutionary Hard Seal technology. Unlike soft-seated valves vulnerable to wear and tear, the Hard Seal Super Hard Ball Valve features precision-engineered sealing surfaces crafted from ultra-hard materials. These critical components undergo specialized surface hardening treatments (such as thermal spraying, overlay welding, or specialized nitriding), achieving exceptional surface hardness (typically exceeding HRC 60 or higher). This super hard barrier delivers:

• Unrivaled Abrasion Resistance: Withstands severe erosion from slurries, catalysts, fly ash, coal-water mixtures, and other highly abrasive media, drastically extending service life.

• Superior Corrosion Resistance: Maintains integrity against aggressive chemicals and corrosive environments common in chemical processing, mining, and metallurgy.

• High-Temperature & High-Pressure Performance: Engineered seals and robust construction ensure reliable operation under elevated temperatures and pressures.

• Bubble-Tight Shutoff (Zero Leakage): Achieves exceptional sealing performance (meeting or exceeding ANSI/FCI 70-2 Class VI or equivalent standards), critical for safety, environmental compliance, and process efficiency.

• Reduced Maintenance & Downtime: The extreme durability of the super hard sealing surfaces translates to significantly longer maintenance intervals and lower total cost of ownership.

Engineered for Critical Applications

The Accton Hard Seal Super Hard Ball Valve is the optimal solution for industries demanding maximum reliability under punishing conditions:

• Power Generation: Fly ash handling, FGD systems (limestone slurry), coal slurry transport, bottom ash systems.
