Founded in 1874 by Joseph Watts, Watts Regulator Company, as they were originally known, made its reputation by "Setting The Standard in Valve Technology." During its early days, Watts manufactured pressure reducing valves to regulate steam and relief valves to ensure safe operation of water heaters and boilers.
