Types of Valve
Intake Valve
Mono-Metallic ValveMono-metallic valves are only made from one material. For this, one material is chosen that is suited to both requirement profiles, namely high heat resistance and good sliding properties.
Exhaust Valve
Bimetallic valveBimetallic valves enable material combination of a highly heat resistant agent (headpiece) with a skirt material which can be hardened on the one hand (skirt end) and also has good sliding properties for valve guidance. The materials are combined through friction welding.
