Eaton is the leading global supplier of engine valves with total production of more than one million engine valves per day, supplying nearly all vehicle and engine manufacturers worldwide.
Solutions such as hollow valve manufacturing, seat welding, salt bath nitriding, and continuous materials development overcome the issues of increased temperatures, combustion pressures, corrosion and seat wear.
For more than 85 years, Eaton has been designing and developing engine valve technologies for manufacturers that require high quality valves for gasoline, diesel and alternative fuel engines.
Eaton differentiates itself by using innovative technology to produce engine valves.
Engine downsizing coupled with increased power density requires valves with higher strength and temperature resistance. This challenge can be addressed with high performance materials, special seat and stem coatings, lightweight and hollow valves, which enable internal cooling.
Eaton hollow valves ensure engine knocking reduction enabling fuel economy, catalitic converter efficiency and specific power increase
Improved wear resistance
Proven reliability for increased power
Crutonite (EMS 200) is Eaton's Automotive News PACE Award-winning, proprietary high-temperature exhaust valve alloy with reduced nickel content.It can be used on intake or exhaust valves.
