What LibertyCES's vendor documentation shows
Same shared 8-chemical reference table used across Crane's lined valve family names these acids.
Materials documented for this service
- PFA/PTFE lining
- Ductile Iron body
Products cited for this service
Real Specifications
| Crane XLC size & pressure | 1/2"-12", ASME B16.5 Class 150 flange rating, PFA Teflon-lined ductile iron body, solid PTFE Teflon ball | crane-cpe-xomox-lined-valves.md |
| Crane XLC named chemistries | Sulfuric Acid, Nitric Acid, Hydrochloric Acid, Phosphoric Acid named in the shared 8-chemical reference table | crane-cpe-xomox-lined-valves.md |
| Richter BC/CV size, pressure, temp | ASME 0.5"-6" / ISO DN15-DN100, Class 150/16 bar, -60°C to +180°C | richter-ct-check-valves.md |
| Richter BC/CV lining | PFA lining, 4-5mm thick, suitable for vapors/gases as well as liquids | richter-ct-check-valves.md |
Richter rates the BC/CV for vapors and gases, not just liquids — worth checking on any acid service where off-gassing is possible, since a liquid-only check valve is the wrong spec even when the pressure class looks fine on paper.
The same 8-chemical list — sulfuric, nitric, hydrochloric, phosphoric acid among them — appears on 6 of Crane's 8 lined-valve products, meaning it's one shared reference table reused across the family rather than 6 independently tested results; real data, worth confirming the specific concentration and temperature with the vendor rather than treating it as per-product testing.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
