PRODUCTION | CYLINDER HEAD and COMPONENTS

Optima boasts a few cylinder heads for heavy-duty engines.

Optima intake and exhaust valves are available in forged and hot-extruded versions. Depending on their field of application, they are armored or hardened and have a nitrided or chrome-plated surface. Valves that are exposed to particularly high peak cylinder pressures or temperatures can be manufactured as sodium-filled hollow valves.
