16- Advantages for Ultra high purity gas
- Metallic bellows seal type
- very high sealing (1.10-9 mbar.l/sec He)
- Plug material according to the application
- Metal, Ni, PCTFE, PTFE, Vespel
- No pollution
- metal to metal sealing to atmosphere
- (1.10-9 mbar.l/sec He)
- electro-polishing 0.2µm (up to)
17- Advantages for nuclear application
- Forged body
- very small risk of fissure or porosity in the
body - Stainless steel parts
- very good compatibility with gas (corrosive
gases, radioactive gases)
