Atwood & Morrill®

Atwood & Morrill began in 1900 in Salem, Massachusetts, making valves for mills in the United States. As a pioneer in valve design engineering, Atwood & Morrill manufactures large valves for power plants, including the first prototype nuclear reactor, and the United States Navy’s first nuclear submarine.
