What material should a butterfly valve for Xylene (C₈H₁₀ - Ortho, Meta, Para) be?

Carbon Steel (Excellent): Standard for xylene storage and distribution. SS 316L (Excellent): Preferred where corrosion protection is required. PTFE seals (Excellent): Best elastomer choice - resistant to xylene. Viton (FKM) seals (Good): Acceptable for xylene service.

Governing Standards for Xylene (C₈H₁₀ - Ortho, Meta, Para) Service

API 607 (fire testing)API 6D ASME B16.34ATEX 2014/34/EU

What to Avoid in Xylene (C₈H₁₀ - Ortho, Meta, Para) Service

NBR or EPDM-seated valves - xylene degrades these elastomers
Non-fire-safe valves in ATEX Zone 1 process areas

Service Considerations

Fire-safe API 607 valves mandatory in all xylene process and storage areas
PTFE or Viton seals only - NBR and EPDM are incompatible with aromatic hydrocarbons
ESD valves on storage tank connections in PX (para-xylene) plants
Acetic acid corrosion in PTA oxidation circuits - Hastelloy C-276 required for high-acid streams
