Abstract: In a valve housing for a globe valve for controlling a process fluid flow of a process plant (e.g. a chemical plant, petrochemical plant, a power plant, or a food processing plant), a passage opening is provided that can be closed by a valve member movable translationally in a vertical direction. The valve housing may define, in the vertical direction above the passage opening, a working space for accommodating the valve member. The valve housing may define a kettle space in the vertical direction below the passage opening. The valve housing may include at least one guide blade projecting radially into the kettle space for disturbing a process fluid vortex with vertical vortex axis of rotation filling the kettle space.

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).
