Emerson, whose headquarters are located in Missouri, USA, has gained DNV-GL approval for its ASCO 551 and 553 series solenoid valves. This means that the valves comply with the soon-to-be-introduced (September 2017) worldwide regulations for ballast water treatment. From this date, all valves used for treating and managing ballast water aboard ships must comply with the new standard.
The 551 and 553 Series are certified for use in functional safety loops such as may be found on LNG vessels and tankers. This broad range of applications makes it easier to standardise on one solenoid valve, simplifying on-board maintenance.
DNV-GL approval combines two standards: DNV (Det Norske Veritas) and GL (Germanischer Lloyds). The introduction of the new standard is set to have a major impact on the ballast water industry. In total, around 70,000 boats worldwide will be affected by the new regulation.
