Black Diamond™ valves are CNC machined from one-piece forgings of EV8 Stainless Steel
Lightweight, strong, one piece forging with profiles that provide excellent flow characteristics
Valve is infused by a special German process to a depth of .002, with a surface build up of .0002 which 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 (F.E.A) software, and profiles are tested on a computerized flow bench
Stems are coated with black nitroneg
Made in the USA
Can be run in cast iron and bronze type guides at close tolerances for maximum oil control and heat dissipation.
