  • ENSURE SAFETY – Make no compromise on safety as the “C“ shaped ball eliminates the ball cavity and with it, the inherent risk of trapped product expanding to cause catastrophic valve failure. The valve seat is also fully encapsulated with stainless steel to safeguard against explosive failure.
  • MINIMIZE PRODUCT LOSS – Drive towards maximum process efficiency with a truly zero leakage valve. Torque seating combines with an advanced fixed seat design to deliver assured mechanical sealing one full order of magnitude better than the prevailing industry standard (BS6364).
  • REDUCE EMISSIONS – Lead the way in emission reduction performance with the ²XC torque seating design that eliminates dynamic seals and also features an ultra low emission packing system to meet applicable regulatory requirements.
  • LOWER INSTALLED COST – Engineer cost out of your project with this true bidirectional valve that requires no venting, allowing streamlined pipe routing and fewer isolation valves. The ²XC also features a modern top entry design that is up to 30% lighter than traditional comparable ball valves.
  • CERTIFIED TO PERFORM – Rest assured of process isolation performance with the ²XC that is engineered to meet and exceed the most stringent industry standards and is certified to API 6D, BS 6364, Shell DVT, and SIL 3 capable.
