摘要: The invention relates to a valve attachment (3) comprising an actuator (5), a pin (6) connected to the actuator (5) and a control unit (11) arranged to control the actuator (5). The actuator (5) is arranged to displace the pin (6) and the valve attachment (3) is structured and arranged to be attached to a valve housing (2) such that a displacement of the pin (6) also displaces a valve element (9) arranged in the valve housing (2) if the pin (6) abuts a stem (8) arranged in the valve housing (2). The stem (8) is connected to the valve element (9). Task of the invention is to provide a valve attachment that can prevent the occurrence of a gap between the pin and the stem during operation of the valve attachment. According to the present invention the above task is solved in that the valve attachment (3) comprises at least one reactance sensor (16, 18, 22) to detect if a gap (15) is present between the pin (6) and the stem (8).
