Our diesel performance valves are designed to perform reliably in the extreme conditions that exist in highly boosted turbo diesel engines. Bi-metallic exhaust valves are made from inconel and HNV-3 alloys and are stellite faced to operate under extreme heat conditions. Intake valves are made from 21-4N alloy steel. Both intake and exhaust valves are put through our proprietary five step liquid nitriding process, resulting in valves that are smoother, stronger and more corrosion resistant than traditional chrome plated stainless valves.
21-4N high strength stainless alloy
Swirl polished for improved flow characteristics
Fully undercut stem
Hard wafer tip
One piece forging
Proprietary liquid nitriding process that creates a valve that is smoother, stronger and more corrosion resistant than traditional chromed valves
Deep nitriding provides better ductility under the hard nitrided layer as proven in rotating-bending fatigue tests
Valve is less likely to break even if contacted by the piston
Greater surface hardness means less valve guide wear
Improved corrosion resistance even with exotic fuels
Our nitriding process is much cleaner than chroming- it’s better for the environment
