Meto Rotary Control ValveMetso’s enhanced Neles Finetrol rotary control valve achieves the ISO 15848-1 class BH fugitive emission-type approval certificate in class CH-3 (100 000 mechanical cycles). It has reduced control variability and lower flow media consumption. Improved control performance is intended to enhance end-product quality, decrease valve reversals, and reduce energy consumption. Better valve performance and gland-packing tightness means less maintenance and longer valve life cycle. The requirements of the ISO 15848-1 class BH emission level constitute a simple, cost-effective way to decrease overall fugitive emissions, which provides a safer process environment and a cleaner atmosphere. The high-performance packing tightness also improves reliability and efficiency while preventing the loss of both raw material and end product. The approval certificate covers the full 1-inch to 10-inch size range and ASME #150 and #300 pressure classes. – metso.com
