Valves for Xylene (C₈H₁₀ - Ortho, Meta, Para) Service
Xylenes are aromatic hydrocarbons produced from catalytic reforming and coal tar distillation, widely used as solvents and as feedstocks for PTA (purified terephthalic acid, the monomer for PET polyester). Para-xylene (p-xylene) is by far the most commercially important isomer, processed in UOP Parex / Axens Eluxyl continuous adsorptive separation units at moderate pressure. Xylene is flammable (flash point ~25–30°C) and a mild CNS hazard; its main valve demands are fire-safe design and solvent-resistant elastomers.
Pressure Range

What valves are used for Xylene (C₈H₁₀ - Ortho, Meta, Para) service?
Ball Valve (WCB, fire-safe, PTFE seat) are recommended for Xylene (C₈H₁₀ - Ortho, Meta, Para) service: Standard isolation for xylene pipelines and tank connections in aromatics complex.
Key Properties - Xylene (C₈H₁₀ - Ortho, Meta, Para)
- Flash point ~25–30°C (depending on isomer) - flammable liquid, ATEX Zone 1 in process areas
- Good solvent - attacks many rubber elastomers and paints
- Non-corrosive to steel, SS, bronze
- Handled in liquid phase at near-ambient conditions in aromatics plants
- PTA oxidation reactor uses acetic acid + xylene mixture at elevated temperature

Material Compatibility - Xylene (C₈H₁₀ - Ortho, Meta, Para)
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) | Excellent | Standard for xylene storage and distribution. |
| SS 316L | Excellent | Preferred where corrosion protection is required. |
| PTFE seals | Excellent | Best elastomer choice - resistant to xylene. |
| Viton (FKM) seals | Good | Acceptable for xylene service. |
| EPDM / NBR seals | Poor | Both swell in aromatic hydrocarbons - not acceptable. |
