All KPMI® Black Diamond™ Stainless steel valves are impregnated by a special 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 resistance to corrosion and wear that is 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, strong, one piece forged with profiles that provide excellent flow characteristics.
