<p>A control valve for radiators, which has an electromechanical drive and in which a valve controlling the through flow of a heating medium is controlled as a function of the room temperature, has a housing which consists of two parts (1, 13) connected releasably to one another and in one part (1) of which, preferably in the part fastenable to the radiator, the electromechanical drive, for example a servo-motor (10), is located and in the other part (13) of which are located the control (12) connected releasably to the servo-motor and, if appropriate, a current source, for example a battery (11). The valve may include a manual actuation facility (Fig.3), an end-position switch-off facility (Figs. 5, 6) and frost protection (Fig. 8). <IMAGE></p> |
