Engine Valves

Black Diamond TM Valves KPMI Black Diamond™ one pieced forged stainless steel valves are impregnated by a special German process to improve wear properties and reduce friction. Black Diamond™ valves undergo a proprietary post production heat treatment process that hardens the surface of the valve to a depth of about .002”, while leaving a ductile core.

White Diamond TM Valves KPMI fully CNC machine their White DiamondTM valves from a one- piece forging of either EV8 Stainless Steel or Inconel-751. These materials have proven heat and corrosion resistance properties and are hard chromed with a 30 degree anode to produce the highest possible grade of hard chrome finish.
