Real Specifications

D40 combination air valve pressure range0.2-16 bar, air release + air/vacuum, same rolling-seal technology as DG10netafim-mining-heap-leaching.md
D-series material spreadReinforced nylon, polypropylene, PVDF, 316 stainless steel, super duplex, and Hastelloy springs — corrosion-resistant material spread shared across both copper SX/EW and gold/silver cyanide servicenetafim-mining-heap-leaching.md
The same D-series air valve family serves both copper SX/EW raffinate and gold/silver cyanide circuits — its real qualification for either brine isn't a single named chemical rating, it's the corrosion-resistant material spread (super duplex, Hastelloy springs) built to survive whichever brine chemistry a given leach pad is actually running.

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.
