Metso?s newly de?si?gned Neles Fine?trol rotary control valve has achieved ISO 15848-1 class BH fugitive emi?ssion type approval certi?ficate in the most de?m??a??nding endu?rance class CH-3 (100,000 mecha?nical cycles). The new design reduces health and safety risks, because leakage from gland packing can cause se??rious damage to per?sonnel and to the imme?diate sur?roundings, parti?cularly when noxious flow media are involved. Furt?her?more, direct savings can be achieved due to reduced control variability and lower flow media con?sumption.
