| Applies when | chlorine, chlorine gas, liquid chlorine, chlor-alkali |
|---|---|
| Avoid | standard trim, non-vented ball (Valve) |
| Recommend instead | AVCO Valve Chlorine Service Ball Valve (1100/1900 Series platform) (Valve) |
| Rationale | AVCO Valve's dedicated chlorine service ball valve complies with Chlorine Institute Pamphlet 6, appropriate for Chlorine Service Classes I & IV - a real, named industry chlorine-handling standard. Configuration: carbon steel (WCB) body/ends with ball, stem, and retainers in Monel 400 or Hastelloy C (full-Monel or full-Hastelloy also offered for further internal corrosion protection); the ball is vented to provide pressure relief during operation, the same off-gassing/pressure-relief engineering pattern already established for sodium hypochlorite service (Hayward TBH Z-Ball, Richter GU/GUT overflow valves) but applied here to chlorine gas/liquid specifically. B7 body bolts and 2H nuts for added strength. Available as the 1100 Series platform (full port, minimal pressure drop) or 1900 Series platform (V-ball, Cv-selected) when throttling control is needed. |
