Abstract:
1. A control device for a technical processing plant, comprising: a pneumatically driven actuator having an actuator arm with a connected actuator stem; a valve operated by the actuator, said valve having a valve stem arranged in axial prolongation of the actuator stem; a valve element attached to the valve stem; a stem connector connecting the valve stem and the actuator stem to each other for a forced transmission of axial, translational actuating movements and for modifying an axial distance between adjacent ends of the valve stem and the actuator stem in order to adjust a total axial length of the valve stem and the actuator stem; the stem connector comprising two half-shells to be connected to each other, and first and second positioning devices for a friction-locking coupling of the half-shells to the respective ends, at least the first positioning device being designed to modify an axial attachment position of the half-shells along one of the stems; the second positioning device comprising an encompassing contour formed by said half-shells at an area facing the valve stem, said contour cooperating with a head at the end of the valve stem for axially coupling the half-shells to the valve stem; at an area of entry into a housing of said actuator a display formed at an outer side of the actuator stem for visualizing a position of the valve element; and the display being at least partially covered for a first axial distance between said ends of the valve stem and the actuator stem, and not being covered or being covered less for a second axial distance between said ends of the valve stem and the actuator stem, said covering being performed by said half-shells.
