All-metal Gate Valves DN350CF

In the injection and extraction sections of the SIS100, beam dynamics requirements necessitate vacuum chamber and component apertures of up to approximately 320 mm to contain both the orbit beam and the injected or extracted ion beams. To isolate vacuum sections from one another during maintenance work, all-metal slide valves with a DN160 aperture are used throughout the SIS100; in the injection and extraction areas, all-metal slide valves with a DN350 aperture are required. A total of three of these valves are to...
