Exclusive Internal Stuffing Box to prevent catalyst bypass, Stem mounted Check Valve, Patented catalyst control feature, Hardfacing added for added erosion resistance
Several licensors utilize plug valves to control the catalyst flow in their units in lieu of slide valves. TapcoEnpro's enhancement to the original plug valve design includes an Internal Stuffing Box. The internal stuffing box prevents catalyst bypass from the regenerator to the air inlet tee-section. The internal stuffing box feature is under patent #4,827,967. Another feature available for the plug valve is the Internal Check Valve mounted in the stem tube. The internal check valve prevents catalyst from falling into the stem tube and tee-section in case of air supply failure. The internal check valve feature has been patented by TapcoEnpro under patent #4,813,817. The result is a custom design, tailored to your individual requirements, providing trouble free operation and unmatched service life.
