About c-m-c.com
Welcome to the Carl M Cummings Manufacturing Company (CMC). Our roots go back to the 1920s, when we were part of TRW. In 1960, TRW spun off its valve manufacturing division, and CMC continued manufacturing valves with the same technology in Southern California. A subsidiary of Maven Engineering, CMC is dedicated to quality and reliability. Our valves are used in locomotive, marine and industrial engines around the world.
