Münster are making efforts to supply highly functional engine valve that can support not only durability, downsizing, weight saving, but also leading-edge design such as the improvement of fuel efficiency and low emission.
The engine valve plays an important role in the combustion chamber inside the engine.
As engine valve opens and closes several thousand times per minute in combustion over 800°C, heat resistance and wear resistance are essential.
