Install / Failure Note

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.
