Abstract (en)
The valve has a valve shaft (1) made up of two parts, namely an upper shaft part (2) and a lower shaft part (3). The shaft parts are telescoped together and joined in a connecting area (4) that is made up of two axially separate special joining areas. The upper shaft is welded to a valve cone (6) sealed by a valve tray (5), where outer areas of the valve cone and the lower shaft part have same outside diameter. Hollow spaces exist between the lower shaft part and the valve cone in a form of an annular space and within the lower shaft part in the form of a hollow cone.
