Abstract

A method for manufacturing a lightweight valve is provided. The lightweight valve includes a valve stem, a hollow valve cone and a valve disk closing the valve cone, the valve stem being provided with a hollow space at an end facing the valve disk, the valve disk also having a force transmission element extending through the hollow valve cone into the stem hollow space. The method includes producing a first one-piece component forming the valve disk with the force transmission element by casting, forming and/or a powder metallurgy method, producing a second component forming the valve stem and the valve cone and joining the first and second components together and connecting them by a material, non-positive and/or positive connection.
