Fourteen different ball valves in the TRIAC family feature a live-loaded packing system that meets the TA-LUFT emissions standard of less than 1 ppm, enabling these valves to reduce fugitive emissions and lost product by 99% or more compared to legacy control valves. They employ a unique live-loaded pyramidal stem-packing system having a patented 45-deg. pyramidal stem, a stem seal with Belleville washers, and Grafoil stem packing. Designed with a patented automation pad that allows direct mounting of ISO-5211-compliant actuators, the valves eliminate the cost and fabrication of special couplings or brackets.
