Abstract

The invention relates to a control valve for adjusting a process fluid flow of a process plant, comprising a valve housing (4) with a valve seat (10) and a valve piston (12) connected to a valve rod (14), which valve piston (12) interacts with the valve seat (10) for opening and closing the control valve (2). The invention is characterized in that, for connecting the valve rod (14) to the valve piston (12), a flange (22) is mounted on the valve rod (14), which flange (22) is screwed to the valve piston (12) via plural threaded connecting elements (34; 48).
