Engineered Controls International manufactures RegO products. In 1908, the first RegO products were designed for the gas welding industry. The name RegO was derived from the words regulator and oxygen. RegO product engineers, in conjunction with liquefied petroleum gas marketers, pioneered the development of propane valves and regulators to meet the needs of the rapidly growing industry. The RegO MultiValve illustrates Engineered Controls International s tradition of innovation. In the 1930s, the MultiValve was designed to combine several valve functions in one unit. This made more practical tank designs possible with fewer openings and smaller, less cumbersome protective hoods. MultiValve has kept pace with the changing liquefied petroleum gas industry by continuing to keep tank fabricating cost down and reducing operating expenses for liquefied petroleum gas dealers. The company maintains a location in Whitsett, N.C.
