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. Special...

Temperature sensor Without thermowell With thermowell Type 43-2 N with Type 2430 K Control Thermostat and temperature sensor Valve with welding ends Valve with threaded ends Installation Valve –– Any mounting position is possible. However, preferably with the thermostat suspended downward. –– The direction of flow must match the direction indicated by the arrow on the body. When using a thermowell, the following points must be observed: –– Only use SAMSON thermowells. –– Only the combination of the same kind of materials is permitted, e.g. a stainless steel heat exchanger with thermowells made...
