Rodney Hunt was founded in 1840 to support the equipment needs of the local growing textile industry. Products included plows, wooden water wheels, and gates.
In time, it was decided to focus on the design and manufacture of products serving the growing water control industry. In 1991, Rodney Hunt purchased AC Valve, Inc (Allis-Chalmers) to expand its comprehensive gate and valve range.
In 1995, Rodney Hunt merged operations with GA Industries. Rexnord acquired both companies in 2008, and Fontaine Industries was added to the family in 2009.
