The metals and mining industries present extreme processing environments that severely punish most valves. Severe service metal-seated ball valves’ ability to operate and isolate in extreme environments with corrosive and abrasive solids has made them the preferred product for isolating and directing the flow of hot slurry within POx and HPAL autoclave applications and slurry systems. To withstand the harsh environment, these ball valves require protective thermal sprayed coatings to minimize wear and corrosion, maximizing valve sealing life in these severe applications.
