Märkisches Werk

Märkisches Werk (turnover approx. € 75
million) in Halver in Germany produces
inlet and exhaust valves for engines, ranging
from small valves with applications in motor
sport (20 grammes) to very large valves for ocean tankers (2 metres, 350 kg.).

Europe is its main market (55%), but the German-made products are also sold in the US (30%)
and Asia (15%). One of the technological challenges it faces is to find new materials
and coatings that can meet the different requirements arising from the growing use of
alternative fuels (gas) and mixtures.
