Abstract
A control valve incorporates a valve housing with a main body having a valve inlet and valve outlet, a valve seat in the flow duct between the valve inlet and valve outlet, a valve cage in the flow duct between the valve inlet and valve outlet, and a valve member which is movable in the axial direction (a) relative to the valve seat and valve cage and connectable to an actuator rod of a drive via a drive rod. The valve housing has an extension body extending the main body in the axial direction (a) and a valve cover which closes the extension body and through which the actuator rod can sealably pass. The control valve further includes a circulation barrier in the valve housing which prevents circulation of a process medium in the extension body. The circulation barrier and the valve cage are in contact with each other via contact pressure surfaces opposite one another in the axial direction (a). The circulation barrier and valve cage components are jointly fixed in the valve housing via a fastening means.
