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.
- Exotic inconel alloy is designed to function in extreme heat and stress conditions
- Stellite facing creates additional heat resistance on the head of the valve
- Liquid nitriding strengthens the entire valve material - not just the surface area
- Better ductility beneath the extremely hard magnetite outer layer makes the valve less likely to break, even if contacted by a piston
- Greater surface hardness reduces crack formation
- Smoother, stronger surface means less valve and valve guide wear than chrome
- Resists corrosion and deposits caused by exotic fuels
