Valves, valve seat inserts, and valve guides

In conjunction with valve seat inserts and guides, valves form a system, which must withstand maximum loads. MAHLE 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.
