The company was established in 1891, a few years after founder, William Penn Powers, invented the Vapor Disk Thermostat. This product innovation, the grandfather of today’s room thermostat, was proudly displayed at Chicago’s Worlds Fair in 1893.
The company would later expand on this technology, and come to dominate automatic temperature control for commercial buildings. Leveraging their core competency in temperature control, The Powers Regulator Company developed the first modern Pressure Balance Valve in 1924, bringing bather safety and comfort to modern plumbing.
