Request a Spec Review →Yes. LibertyCES has documented Pilot-Operated Control Valve in Mining / Heap Leaching applications, including Netafim 90 Series, Netafim 100 Series and Netafim Flushing Valve with Timer. The right model depends on the fluid, concentration, temperature, flow and duty cycle, so send James your process data for a free spec review before final selection.

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| 75 Series pressure & temperature | 3/4"-4"R: 10 bar/145 psi; 3"H-8"R: 12 bar/175 psi; both 60°C/140°F max | Netafim Mining — Heap Leaching Products Catalog |
| 90 Series pressure & temperature | 8-10 bar/115-145 psi (size-dependent), 40°C/104°F max | Netafim Mining — Heap Leaching Products Catalog |
| 100 Series pressure | 16 bar/230 psi or 25 bar/365 psi, metal body (cast iron/ductile iron/bronze/stainless) | Netafim Mining — Heap Leaching Products Catalog |
| ALD70 diaphragm sulfuric acid rating | 38°C max — far more restrictive than the body/liner materials at the same acid concentration | Netafim Mining — Heap Leaching Products Catalog |
On a sulfuric heap-leach quote, the ALD70 diaphragm — not the body or liner material — is the limiting component at only 38°C max; ALD70 is also rated Not Good for nitric acid even at 10%, chlorine dioxide, and chlorine gas, with Hastelloy named by Netafim's own catalog as the substitute for those three chemistries specifically.
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 — Netafim's own chart puts ALD70's ceiling at 38°C, which is the number that decides whether this valve survives the application, not the pressure rating on the nameplate.
