Request a Spec Review →Named chemicals
LibertyCES has documented Actuated Valve in Oxidizers/Disinfectants service, including Chlorine Gas, Chlorine Dioxide and Sodium Hypochlorite. Wetted materials to confirm: ALD70 diaphragm and Hastelloy. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
Netafim's ALD70 diaphragm chemical resistance chart gives hard fail ratings for chlorine gas, ClO2, and hypochlorite, requiring Hastelloy upgrade.
Materials documented for this service
- ALD70 diaphragm (fails on Cl2/ClO2/NaOCl)
- Hastelloy (upgrade)

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| ALD70 diaphragm — Chlorine Gas & Chlorine Dioxide | Both rated "Not Good" on Netafim's own ALD70 diaphragm chemical resistance chart | Netafim Mining — Heap Leaching Products Catalog |
| ALD70 diaphragm — Sodium Hypochlorite | Limit 80°C @ 100 mg/L; Limit 30°C @ 170 mg/L — a concentration-and-temperature-dependent rating, not a flat pass | Netafim Mining — Heap Leaching Products Catalog |
| Hastelloy upgrade rationale | Netafim's own catalog states Hastelloy "is resistant against chlorine gas, hypochlorite and chlorine dioxide solutions" — the vendor-named substitute for all three chemistries where ALD70 fails | Netafim Mining — Heap Leaching Products Catalog |
ALD70 rates a flat 'Not Good' for chlorine gas and chlorine dioxide regardless of concentration — an actuated diaphragm valve running either chemistry through a standard ALD70 diaphragm is a documented failure, not a marginal-service risk; Hastelloy is Netafim's own named substitute.
The valve body can be rated for a chemistry the diaphragm inside it flatly isn't — Netafim's own chart puts chlorine gas and chlorine dioxide at 'Not Good' for ALD70 even though the body/liner materials elsewhere in this family tolerate much harsher service. That's the kind of component-level gap a full application review catches and a body-spec-only quote misses.
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.
