Burchard Horne acquires Watts Regulator

In 1918, Watts Regulator was purchased by Burchard Everett Horne (B.E. Horne), transforming the company into a family-owned and operated business. Horne would seek to expand Watts Regulator’s product offering, paving the way for the development of the patented and revolutionary combination temperature and pressure valve.


Introduced T&P Relief Valve

To prevent boiler explosions, two risk factors need to be managed: temperature and pressure. In response to this dangerous problem, Watts introduced the first ever Temperature and Pressure Relief Valve (or T&P Valve), designed to regulate boiler temperature by draining superheated water once a specific temperature or pressure threshold was exceeded. Watts led the charge educating the industry on the need for this pioneering technology, working to establish a national safety standard and specify T&P valves in safety codes.
