Valves

The inlet and outlet valves are powered by the distribution and camshaft to ensure that fresh air (and fuel) enter the cylinder and exhaust gas exits the cylinder. The inlet valve is usually larger than the outlet valve to allow as much mixture as possible into the combustion chamber. The valves are subjected to high thermal loads which must be removed via the valve stem and valve retainer cap. The inlet valves become less hot than the outlet valves and are therefore made of a different material. In some cases, valves are still filled with sodium for even better heat removal. These valves are also hollow inside. However, this construction is only used in outlet valves, as they become warmer than the inlet valves.

Here you will find the right valves and accessories for your engine block, such as valve springs and valve guides. When fitting new valves, it is advisable to replace the valve guides immediately, as everything has to be opened at that time. If you have any questions or would like advice, please contact our product specialists.
