  • TROUBLE-FREE OPERATION – Enjoy smooth operation over an extended high cycling life with the cavity free design that eliminates the opportunity for product to build up in the cavity, harden and impair operation of the valve. The ²XC is also completely safe for volatile fluids that can expand, decompose or ignite in trapped cavities.
  • OPTIMZED SEALING – Rely on the ²XC’s fixed seat to provide repeatable, ultra tight shutoff with a design that eliminates the use of springs and yet another opportunity for product build up that can result in fouling, seat contamination, and premature valve failure.
  • MINIMIZE PARTICLE DAMAGE – Achieve longer lasting tight shutoff in severe service applications with a cam motion that creates low friction and thereby minimizes particle damage. In contrast, traditional ball valves with a concentric motion are highly susceptible to sealing service wear.
  • PARTICLE SWEEPING – Minimize stress on valve closure with a convex to convex seat design that sweeps particles in the last 2-3 degrees of motion rather than compressing impurities into the valve trim to maintain seal integrity.
  • INPENETRABLE PROTECTION – Take on abrasive particle applications with a valve architecture that allows 100% unbroken HVOF coating of the ball surface. With no start or end point, the hard wearing coating is extremely resistant to wear and is able to close on particles without damage.
