2012 was a banner year at the Metso Flow Laboratory, where a corporate initiative to increase the numbers of valves certified to the most stringent environmental emissions standards continues. In 2012, numerous Neles metal-seated and Jamesbury soft-seated valve products were certified to meet the requirements of the global ISO15848-1 standard, complying with many standards mandated in specific regions, including TA-Luft (Germany) and EPA 40 CFR parts 60/63 (USA).
ISO15848-1 certified valves are regarded as fulfilling the most stringent emission standards, and meeting this qualification signifies compliance with many other emission standards. It is also a mandatory requirement of the majority of current projects in the oil and gas industries worldwide.
Metso’s control and on-off valve product series include ball, butterfly and eccentric rotary plug valves in pressure classes ASME #150-600. In 2012, representative products from these series were shown to meet ISO15848-1 requirements for:
-Highest temperature class (+400º C with graphite packing) for metal seated valves and (+200 º C with PTFE packing) for soft seated valves
-Low leakage class (B)
-Class A (bellows seal tightness) of the Neles D1F series cryogenic valves with graphite packing
