The Trillium Flow Technologies™ legacy brand Atwood & Morrill® began in 1900 in Salem, MA, USA. The company started out making valves for mills in the USA and later produced valves for ships during World War II. The company has also manufactured large valves for power plants, including the first prototype nuclear reactor, and for the U.S. Navy’s first nuclear submarine.
Today, as one of Trillium Flow Technologies™ innovative legacy brands, Atwood & Morrill is proud to be a pioneer in valve design in engineering in power generation, oil and gas, and petrochemicals.
