Valves for Diesel Fuel / Fuel Oil Service
Diesel and fuel oil (HSD, LDO, HFO) are widely used petroleum products handled in refineries, terminals, power plants, and marine vessels. Relatively benign on materials - carbon steel is standard. Key concerns are vapour emission control and fire-safe valve design.
Pressure Range
1–25 bar
Temperature
Ambient to 120°C (HFO heated service)
Industries
Fuel storage terminals, Power plant fuel handling, Marine bunkering
What valves are used for Diesel Fuel / Fuel Oil service?
Carbon steel ball valve (API 607 fire safe) are recommended for Diesel Fuel / Fuel Oil service: Standard for diesel fuel terminal and refinery service.
Key Properties - Diesel Fuel / Fuel Oil
- Carbon steel is the standard material for all diesel and fuel oil service
- Flash point: HSD ~52°C, HFO >60°C - fire-safe valves required
- Heavy fuel oil (HFO/Bunker C) is viscous - heat tracing required below 50°C
- Waxy crude fractions may precipitate in dead-legs below pour point
- Marine diesel: biocide addition can affect elastomers

Material Compatibility - Diesel Fuel / Fuel Oil
Ratings are indicative. Actual compatibility depends on concentration, temperature, velocity, and presence of contaminants. Always consult corrosion tables or a materials engineer.
| Material | Rating | Notes |
|---|---|---|
| Carbon Steel (WCB/A105) | Excellent | Standard for all diesel and fuel oil service. |
| Ductile Iron | Good | For low-pressure fuel oil systems. |
| SS 316L | Excellent | Preferred for marine and food-grade fuel handling. |
| NBR (Nitrile) | Excellent | Excellent for fuel oil seals and seats. |
| PTFE | Excellent | Standard for valve seats in fuel service. |
| EPDM | Poor | Not compatible with petroleum products - EPDM swells in hydrocarbons. |
