The temperature regulators work according to the adsorption principle. The temperature of the measured medium creates a pressure in the sensor which is proportional to the measured temperature. This pressure is transferred through the capillary tube (12) to the operating element (10) and converted into a positioning force. This force causes the pin of the operating element (11) to move the plug stem (4) with the valve plug (3). By turning the set point adjuster (9), the point of response is changed over the valve spring (5). The valves are balanced by a metal bellows (6). The balancing...
