Real Specifications
| D20 air-gap design | Continuous air gap design (conical body/funnel-shaped lower body) physically separates the leach solution from the sealing mechanism, 0.05-16 bar | netafim-mining-heap-leaching.md |
| D-series material spread | Reinforced nylon, polypropylene, PVDF, 316 stainless steel, super duplex, and Hastelloy springs across the D20/D25/D26/D40/D40L family | netafim-mining-heap-leaching.md |
| D40L rating for solids-bearing service | Polypropylene body rated to 10 bar, reinforced nylon-PVDF-Duplex-SST body rated to 16 bar, explicitly for liquids with suspended solids | netafim-mining-heap-leaching.md |
The air-gap design exists specifically to prevent scale and mineral deposits from fouling the seal on closed-loop leach-solution recirculation — a standard direct-float-seal air valve on a sulfuric heap-leach line is the documented failure mode this design was built to avoid.
Sulfuric heap-leach solution recirculates in a closed loop and concentrates dissolved solids over time — an air valve with a direct float seal will scale shut on that same loop, which is exactly the failure mode Netafim's air-gap body was built to avoid.

Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
