A valve tube, which belongs to the diode family of vacuum tubes, is specifically engineered to allow the passage of electric current in a single direction within the tube. These valve tubes find application in circuits for the purpose of rectifying the current. In contemporary valve tubes, the filament is thoriated in order to extend its lifespan.
