Description
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. Black Diamond Valves are light, strong, one-piece forgings with profiles that provide excellent flow characteristics.
