The English Electric Valve Company, or EEV, (now part of Teledyne) began in the early 1940s as a part of the Marconi group, manufacturing magnetron vacuum tubes for Radar systems. EEV was originally registered in 1947 as the “Phoenix Dynamo Company,” but immediately changed its name to English Electric Valve Company. By 1959, EEV was the largest hi-tech manufacturing company in the UK. Historically, it is known for the manufacture of electronic components and sub-systems for aerospace and defense, healthcare, and commercial and industrial sectors.
