November 2010, Valve World Expo will be staged in Düsseldorf. Messe Düsseldorf GmbH has acquired the leading global event for valves and valve accessories from KCI Publishing B.V., based in Zutphen, the Netherlands, which launched the trade fair in 1998 and has been responsible for organising and running the event in the Dutch city of Maastricht every two years since then.
