The range of products is such that a reliable solution can be offered for every vacuum engineering application. Many years of service and the reliability of the valves is ensured by design. Oerlikon Leybold Vacuum valves are well-proven in many widely varying areas of re search and industry.

Product Category : Vacuum Gauges and Controller


The special characteristics of the application in each case result in special requirements concerning
features of the valves, for example:

  • Coating
    Short switching cycles (e.g. 1.5 s)
    Very high number of opening and switching cycles (e.g. over 10 million cycles)
  • Analytical engineering
    High conductance (similar to the corresponding flange components, like bends, for example)
    High integral leak tightness for the valves (leak rates below 10-9 mbar l/s)
  • Lamps and Tubes Manufacture
    Temperature resistant
    Permissible ambient temperatures, 50 °C max.
  • Accelerator Technology
    Materials capable of resisting radiation, high temperatures and corrosion at the same time
  • Metallurgy and Furnace Manufacture
    Rugged and insensitive to contamination
  • Chemistry
    Choice of materials in contact with the medium for the valve body


Switching cycles over 10 million cycles
Leak rates below 10-9 mbar l/s
Ambient temperatures Max. 50 °C
