VALVES stainless steel custom & off-the-shelf
DP ~ KPMI ~ VESRAH

DP and KPMI valves are one-piece forgings made from a stainless steel material known as EV8. This is a heavy-duty, high performance material that many companies will use only for exhaust valves because it is so expensive. They then will use a lesser grade of stainless material for the intake valves. We use the EV8 because we believe it is better to use the best poss

ible material for the exhaust and the intake valves.... more >>

cont.....
KPMI also offers an Inconel exhaust valve (1 pc. forging) for blown and fuel engines and Tensilite valves which are 1 pc. titanium forgings.

The KPMI Black Diamond valve is a valve that has undergone a proprietary multi-stage heat-treatment and surface finish process. This treatment actually reacts with the parent material to create a specific hardness to a depth of .002" while maintaining straightness. Once the desired hardness and surface finish are achieved, the valve undergoes a final treatment, which helps prevent galling. These processes, combined with the high-quality EV8 material have combined to create a valve that is strong and virtually impervious to stem wear.
