We make intake and exhaust valve guides using ferrous or non-ferrous metals. The cast iron (ferrous) is more resistant to wear, while copper based alloys (non ferrous) provide optimal heat conductivity. Then we make valve guides in sintered steel. With self-lubricating properties and greater resistance to high temperatures, these are ideal for aspirated and turbocharged engines with very high performance.
Our ferrous valve seats are made with temperature resistant steel and special cast iron. Then, for greater heat conduction, we make sintered valve seats using metals and carbides with high mechanical and thermal properties.
Made with case-hardening steel, the accuracy of our valve shims is measured in hundredths of a millimetre. This enables them to meet the small tolerances demanded. In fact, the increments of sizes are just five hundredths of a millimetre.
