Governing Standards for Argon (Ar) Service

ASME B16.34ISO 21011 (cryogenic valves)SEMI F36 (semiconductor purity)

What to Avoid in Argon (Ar) Service

  • Non-cryogenic rated valves for liquid argon
  • Valves with dead legs or crevices in high-purity semiconductor service

Service Considerations

  • High-purity argon in semiconductor fabs requires electropolished SS 316L valves, no dead legs
  • Liquid argon requires extended-bonnet valves - same as LN₂ requirements
  • Heavier than air: accumulates in pits and trenches - forced ventilation required
