Key Features
  • Double-ended rectifying valve
  • Water-cooled anode
  • Tungsten filament

Application Notes

Cooling supply must be started before application of voltages. Valve must be supported by its water jacket in a vertical position. Rigid connection to anode only. Peak inverse voltage must not exceed 20kV at switching; use gradual increase or two-position switching for higher voltages.
