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 forgings with profiles that provide excellent flow characteristics.TypeExhaustMaterialBlack Diamond™ StainlessCoatingBlack NitronegQuantityPkg. of 1Head Diameter28.24mm / 1.112″Stem Diameter5.0mm / 0.1955″Tulip10ºOverall Length3.865″RemarksStandard
