Special version –– Sensor of CrNiMo steel Type 2231 Control Thermostat –– Capillary tube made of CrNiMo steel or plastic-coated copper –– Valve free of non-ferrous metal –– Stainless steel valve version –– Dimensions and materials according to ANSI (u T 2115) Principle of operation (Fig. 2) The regulators operate according to the liquid expansion principle. The temperature sensor (11), capillary tube (8) and operating element (7) are filled with an expansion liquid. The temperature-dependent change in volume of this liquid causes the operating element (7) to move and, as a result, also...
