What LibertyCES's vendor documentation shows

The load-bearing finding: Type 800 has a dedicated datasheet specifically for dry chlorine service (CP-XOMOX-HPBVDRYCHLORINESERVICE), not just a general brochure — this line is validated for chlorine gas handling rather than merely marketed for it. Chlorine liquefaction and air separation both appear in the industrial-branch list, and the process list names liquid nitrogen, oxygen and carbon monoxide/carbon dioxide. Sodium hydroxide is explicitly named here and notably was NOT listed on the XOMOX Lined Valves family, so this fills a real intra-brand gap for a NaOH-service butterfly valve.
