For each respective extension a threaded bore is present, which on a lateral wall thereof opens into the extension. The valve rod is connectable to the valve plate by a respective retaining bolt screwed into the respective threaded bore and via an end portion that protrudes from the threaded bore into the extension, with the end portion interacting with a groove on a connecting part connected to the valve rod end, or at the valve rod end is configured integral to the latter.
