Mr. Sloan perfected a strong sales process in the early years of doing business. He would gain permission to set up a Royal for demonstration purposes then let the product sell itself. Since their humble beginnings, the Sloan Company has successfully introduced designs and innovative creations in virtually every ten years since the beginning of the business.
During the 1920’s, the Sloan Company opened a newer manufacturing plant to construct the Royal Flushometer valve in Chicago. When the 1930’s arrived, the Royal was improved with the “segment diaphragms” which extended the valve life and produced quieter operations.
In the 1940’s, Mr. Sloan introduces the vacuum breaker technology in the Flushometer, and patents the “Quiet Flush” features.
Mr. Sloan continues to successfully innovate by inventing hidden flush valves and the patented double hand opening valve bodies in the 1950’s. In the 1960’s, the Sloan Company grew enough significantly to demand a newer more automated factory situated in the Chicago, Illinois suburb, Melrose Park. However, the company will grow without its founder when William E. Sloan passes away at age 93 in 1961.
The 1970’s saw large steps in technology when the Sloan Company introduces the first sensing element electronic flushing scheme. This new unique system called OPTIMA Royal is an immediate triumph and leads to another opening of a plant in Franklin Park, 20 minutes west of Chicago, Illinois.
During the 1980’s, testing has confirmed what Mr. Sloan has constantly claimed: The Royal Flushometer is the longest lasting and most exact Flushometer. The Sloan Valve Company further makes another scientific advancement by perfecting battery powered electronics.
As the 1990’s rolled around, The Royal features a few of the most innovative design characteristics available, a dual filtrated fixed bypass arrangement. The ADA compliant Flushometer continues to lead in water conservation, convenience, and design.
To observe the one hundred year anniversary of the Flushometer in 2006, the Sloan Company introduced the Royal Classic, a reproduction of the original Flushometer.
William E. Sloan improved additional technologies as well as the Royal. As the Sloan Valve Company grew, their company’s product line was augmented by groundbreaking products such as the Crown, the Star, the Naval, and the Gem. The company has also formulated automatic urinal flushing systems including the Act-O-Matic showerhead. More importantly, like Stemmle Plumbing, the Chicago area based company shows no signs of slowing down.
