LibertyCES has documented Chlorine Service Ball Valve in Gases & Elemental/Inorganic Misc service, including chlorine gas, liquid chlorine and wet chlorine gas. Wetted materials to confirm: Carbon steel WCB body and ends, B7 body bolts and 2H nuts and Flowline chart. Documented models include AVCO Chlorine Service Ball Valve. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Materials documented for this service
- Carbon steel WCB body and ends
- Monel 400 or Hastelloy C ball, stem and retainers (full-Monel or full-Hastelloy construction also offered)
- B7 body bolts and 2H nuts
- 25% carbon filled Teflon / Teflon seats
- Flowline chart: 316SS rates only C on bromine vapor 25%, saturated bromine water, wet fluorine gas and aqua regia — while PVDF and PTFE rate E; PVC rates F on those same media

The ball is vented to provide pressure relief during operation — the same off-gassing/pressure-relief mechanism already established for sodium hypochlorite across multiple vendors, here applied to chlorine specifically; a non-vented ball valve on chlorine service is a real crystallization/pressure-buildup risk.
The Flowline chart independently backs up AVCO's Monel/Hastelloy specification here: 316SS is rated only C against the halogen gases and waters in this family, which is the material-science reason behind — not just a marketing claim for — building this valve in Monel 400 or Hastelloy C instead of standard stainless.
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.
