Electronic Vacuum Valve

The type known as a thermionic tube or thermionic valve uses the phenomenon of thermionic emission of electrons from a hot cathode and is used for a number of fundamental.

Electronic vacuum valve. Proportion air sets the benchmark for electronic control with vacuum pressure valves regulators. Vacuum tubes using thoriated tungsten must have a very high degree of vacuum otherwise the positive ions produced by ionisation of gases in the envelope will seriously affect the emission. Vacuum tubes thermionic valves using cathodes with this coating give electron emission at temperatures of between 1500 and 1600 k.
