16ROTAREXGroup


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)

17ROTAREXGroup


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)

18ROTAREXGroup


Advantages for cryogenic application

• K900, HP9000 and Supra Series– Temperature range : -270°C to +250°C– Top entry valve : for cold box under vacuum– Designed for vacuum isolated installation
