Valves for Toluene (C₇H₈) Service
Toluene is an aromatic hydrocarbon solvent used in paints, adhesives, pharmaceuticals, and as a gasoline blending component. It is also a feedstock for TDI (toluene diisocyanate) used in polyurethane foams. In refineries and aromatics complexes, toluene is handled in large volumes at moderate pressure. It is a flammable liquid (flash point 4°C) with good compatibility with most industrial metals and plastics except EPDM and NBR rubber.

Material Compatibility - Toluene (C₇H₈)
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 | Excellent | Standard for toluene service. |
| SS 316L | Excellent | Preferred for pharmaceutical and food-grade toluene. |
| PTFE seals | Excellent | Best elastomer for toluene. |
| Viton (FKM) | Good | Acceptable for toluene at ambient. |
| EPDM / NBR | Not Recommended | Severely swelled by aromatic hydrocarbons. |
