Governing Standards for Diesel Fuel / Fuel Oil Service
What to Avoid in Diesel Fuel / Fuel Oil Service
- EPDM-seated or EPDM-sealed valves (swells in hydrocarbons)
- Non-fire-safe valves where flash point < 60°C
- Globe valves for mainline fuel isolation
Service Considerations
- HFO heat tracing: valves must be jacketed or heat-traced above pour point
- Tank isolation: rising-stem gate valves provide visible position indication
- ATEX Zone 1 classification at fuel loading/unloading areas
- Marine service: requires Lloyd's Register, DNV, or BV type approval
