All KPMI® Black Diamond™ Stainless steel valves are impregnated by a unique German process to a depth of .002, with a surface build-up of .0002. This Black Diamond process improves wear properties, reduces friction, and provides corrosion resistance and wear superior to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Black Diamond Valves are lightweight, solid, and one-piece forgings with profiles that provide excellent flow characteristics.
