Diaphragm Valve for Mining / Heap Leaching

Strong evidence

What LibertyCES's vendor documentation shows

Netafim's 'MIN' mining configuration across 75/90/100 is an ALD70 diaphragm + SST 316 spring, with Hastelloy as an upgrade. The high-value finding lives here: the ALD70 chart rates sulfuric acid at only 38°C max — far more restrictive than the body/liner materials at the same acid — so on a sulfuric heap-leach quote the DIAPHRAGM is the limiting material, not the body. ALD70 is Not Good for nitric acid even at 10%, chlorine dioxide, and chlorine gas; Netafim's own catalog names Hastelloy as the substitute because it 'is resistant against chlorine gas, hypochlorite and chlorine dioxide solutions.'
