What LibertyCES's vendor documentation shows
Diaphragm elastomer, not body material, is the limiting factor even where PVDF/PTFE bodies tolerate higher temps.
Materials documented for this service
- ALD70 diaphragm (38°C max on H2SO4; fails on nitric)
- SST 316 spring (MIN configuration)
Products cited for this service
Real Specifications
| ALD70 diaphragm — Sulfuric Acid | 38°C max — far more restrictive than the body/liner materials at the same acid concentration | netafim-mining-heap-leaching.md |
| ALD70 diaphragm — Nitric Acid | Rated "Not Good" even at 10% concentration | netafim-mining-heap-leaching.md |
| MIN mining configuration | ALD70 diaphragm + SST 316 spring is the standard 'MIN' mining configuration across the 75/90/100 Series valve lines | netafim-mining-heap-leaching.md |
On a sulfuric heap-leach quote, the ALD70 diaphragm — not the body or liner material — is the limiting component at only 38°C max; confirm operating temperature against the diaphragm rating specifically, since the body material's higher ceiling doesn't apply to the whole valve.
Most suppliers would spec this valve off the body material and call it done. The diaphragm elastomer is the part that actually fails first on a sulfuric leach circuit — James checks the component that actually touches the fluid at its worst point, not just the one on the nameplate.
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 Actuated Valve compatible with Acids?
