The Neles Finetrol rotary control valve can achieve certification approval for ISO 15848-1 class BH fugitive emissions in the most demanding endurance class CH-3 (100,000 mechanical cycles). The new design reduces health and safety risks, says the manufacturer, because leakage from gland packing can cause serious damage to personnel and to the immediate surroundings, particularly when noxious flow media are involved. The ISO approval certificate covers the full 1–10-in. size range and ASME 150 and 300 pressure classes. Quarter-turn valve design combined with live-loaded packing is accepted as the most efficient and environmentally friendly solution for all control valve applications due to its low fugitive emissions, says the company. — Metso Corp., Helsinki, Finland
