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
