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) ROTAREX Group 16

SELFA bellows valves

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) ROTAREX Group 17
