The temperature of the medium creates a pressure in the temperature sensor which is proportional to the measured temperature. This pressure is transferred through the capillary tube (10) to the operating element (8) and converted into a positioning force. Depending on the set point adjustment, the positioning force acts on the valve plug (3) over the pin of the operating element (9) and the plug stem (4). By turning the set point adjuster (7), the point of response is changed in such a way that allows the valve plug to pass through its travel in a temperature range measured by the sensor....
