More About Caleffi
Caleffi started in Gozzano, Italy and then moved its headquarters to Fontaneto d'Agogna, where it is today. The company initially manufactured brass and steel fittings and accessories for other valve manufacturers. They have always had high quality and efficiency standards, maintained by their quality control system. In 2007, Caleffi opened a new 35,000 square-foot facility in the Menomonee Valley of Milwaukee.
