In 1950, the Century Instrument Company in Livonia, MI started business manufacturing a diaphragm type pneumatic operator which was rapidly accepted for its reliability and quality. Soon, Century was supplying this actuator as a private label to Hills McCanna, Saunders, and Dow Chemical (aka Saran Lined Piping Co.). This was a profitable arrangement for both Century and its private label customers and this relationship went on for many years.

In the mid 1980s, two of Century`s larger customers moved off in other directions. Hills concentrated on ball valves and other projects, and Dow decided to work with manual diaphragm valves only. This left a considerable hole in Century`s business, which prompted them to sell direct through sales representatives to its largest potential market, the water treatment industry, which they continue to supply to this day. Century has a long and impressive history and customers list in their own right, and many thousands of valves in service under other names as a private label. Century continues to supply actuators for Saunders world wide to this day and also on a smaller scale for Hills
