What material should a check valve for Ethanol / Industrial Alcohol (C₂H₅OH) be?

SS 316L (Excellent): Preferred for pharmaceutical and food-grade ethanol service. PTFE / PEEK seals (Excellent): Best seat/seal material across all ethanol concentrations. Carbon Steel (Good): Acceptable for most ethanol service; some corrosion with dilute aqueous ethanol. Bronze/Brass (Good): Acceptable for utility ethanol service.

Governing Standards for Ethanol / Industrial Alcohol (C₂H₅OH) Service

ASME B16.34 API 607 (fire testing, mandatory ATEX areas)ISO 9001:2015FSSAI (food-grade service)ATEX 2014/34/EU

What to Avoid in Ethanol / Industrial Alcohol (C₂H₅OH) Service

EPDM-seated valves - alcohol degrades EPDM elastomers
Carbon steel for pharmaceutical/food-grade ethanol

Service Considerations

ATEX Zone 1 classification in distillation areas - all valves and actuators must be ATEX certified
Fire-safe API 607 design mandatory in production and storage areas
Fugitive emission control (ISO 15848) for VOC compliance
Food/pharma ethanol: SS 316L polished finish, zero dead legs, CIP-compatible
