What material should a globe valve for Naphtha (Light / Heavy Naphtha) be?

Carbon Steel (Excellent): Standard for naphtha storage, transfer, and blending. SS 316L (Excellent): For process naphtha streams requiring higher corrosion resistance. A217 WC6/WC9 (Excellent): For high-temperature catalytic reformer service (>400°C). PTFE seals (Excellent): Best elastomer for naphtha service.

Governing Standards for Naphtha (Light / Heavy Naphtha) Service

API 607 (fire-safe)API 6D ASME B16.34API 941 (Nelson curves for reformer H₂ service)OISD-118 (India petroleum facility safety)ATEX 2014/34/EU

What to Avoid in Naphtha (Light / Heavy Naphtha) Service

EPDM or NBR-seated valves in naphtha service
Non-fire-safe valves in ATEX Zone 1 areas

Service Considerations

Fire-safe API 607 design mandatory in all ATEX-classified naphtha process and storage areas
Catalytic reformer service: high temperature + H₂ - API 941 Nelson curve compliance required for carbon and Cr-Mo steel valves
ESD valves on naphtha storage tanks - OISD-118 requirement for Indian petroleum facilities
PTFE or Viton seals only - EPDM and NBR swell in naphtha
