What LibertyCES's vendor documentation shows
The most chemistry-specific product in AVCO's catalog and a genuinely new standard for this project: compliance with Chlorine Institute Pamphlet 6, appropriate for Chlorine Service Classes I & IV. The mechanism to publish is the vented ball, which provides pressure relief during operation — the same off-gassing/pressure-relief pattern already established for sodium hypochlorite across multiple vendors (Hayward TBH Z-Ball vent hole, Richter GU/GUT overflow valves, Asahi's factory 1/8" vent hole), here applied to chlorine specifically. The Flowline chart independently supports the Monel/Hastelloy specification: 316SS is rated only C against the halogen gases and waters in this family.
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.
FAQ
Is Chlorine Service Ball Valve compatible with Gases & Elemental/Inorganic Misc?
The most chemistry-specific product in AVCO's catalog and a genuinely new standard for this project: compliance with Chlorine Institute Pamphlet 6, appropriate for Chlorine Service Classes I & IV. The mechanism to publish is the vented ball, which provides pressure relief during operation — the same off-gassing/pressure-relief pattern already established for sodium hypochlorite across multiple vendors (Hayward TBH Z-Ball vent hole, Richter GU/GUT overflow valves, Asahi's factory 1/8" vent hole), here applied to chlorine specifically. The Flowline chart independently supports the Monel/Hastelloy specification: 316SS is rated only C against the halogen gases and waters in this family. This is strong evidence.
What materials are documented for Chlorine Service Ball Valve in Gases & Elemental/Inorganic Misc service?
