    • 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.
    • 提供了一种制造轻型阀的方法。 轻型阀包括阀杆,中空阀锥和闭合阀锥的阀盘,阀杆在面向阀盘的端部处设置有中空空间,阀盘还具有延伸穿过阀芯的力传递元件 中空阀锥进入中空空间。 该方法包括通过铸造,成形和/或粉末冶金法制造形成具有力传递元件的阀盘的第一单件部件,形成形成阀杆和阀锥并且将第一和第二部件 在一起并通过物质,非积极和/或积极的联系连接它们。
