Moderate and deliberately scoped: this is air/vacuum management in a liquid line, not aggressive-gas service, but it belongs here because the medium handled is the gas phase. The finding worth publishing is the D20/D25/D26 continuous air gap design — a conical body / funnel-shaped lower body that physically separates the water or leach solution from the sealing mechanism, so scale and mineral deposits cannot foul the seal. That is a specific answer to closed-loop leach-solution scaling, the documented failure mode for conventional float-seal air valves in mining service.

Frequently Asked Questions

Is Air Release / Combination Air Valve compatible with Gases & Elemental/Inorganic Misc?

Moderate and deliberately scoped: this is air/vacuum management in a liquid line, not aggressive-gas service, but it belongs here because the medium handled is the gas phase. The finding worth publishing is the D20/D25/D26 continuous air gap design — a conical body / funnel-shaped lower body that physically separates the water or leach solution from the sealing mechanism, so scale and mineral deposits cannot foul the seal. That is a specific answer to closed-loop leach-solution scaling, the documented failure mode for conventional float-seal air valves in mining service. Materials to confirm: Reinforced nylon, Polypropylene, PVDF, Stainless steel 316, Super duplex, Hastelloy springs, Fusion-bonded epoxy coating per DIN 30677-2 on cast steel/ductile iron bodies. Specific chemicals include entrained air, vacuum, off-gas from leach solutions, carbon dioxide.
