Leonard Valve Co.


Leonard Valve officially began manufacturing thermostatic mixing valves in 1911, and was incorporated in 1913. The founder, Frederick C. Leonard, was a watch repairman and electrician, among his many talents.

Today, Leonard Valve operates from two facilities in Cranston, Rhode Island, where they have a state-of-the-art machining facility with assembly departments that individually assemble and test each mixing valve and every valve system before shipment.
