View details →About KSB Amri
The AMRI brand traces back to 1959, when a French manufacturer built what became the world's second-largest butterfly valve producer, based in La Roche-Chalais with a research centre near Bordeaux. German pump and valve group KSB acquired AMRI in 1989, making KSB the world leader in cryogenic valves and the French leader in butterfly valves. The AMRI name has continued to change hands since — its North American operations were acquired by Bray International in 2016 and now trade as Amresist — a reminder of how much this market has consolidated around a small number of OEMs.
