The 175 and 153 Series Self-Operating Temperature Regulating Valves require no external power source making them easy to install and maintain. Properly installed, the regulator is capable of maintaining temperatures to within ±3°F. 175/153 Self-Operating Temperature Regulators are actuated by a hermetically-sealed bellows, capillary tube and bulb assembly. The bulb is inserted in the fluid at the point where temperature control is needed. As temperature rises around the bulb, the volatile liquid gas inside the bulb, capillary and bellows expands and transmits a force moving the valve stem downward. Conversely, when the temperature at the bulb decreases, the liquid (or gas) contracts, allowing the regulating spring to compress the bellows and move the valve stem upwards. The regulator can easily be adjusted to any point within its temperature range by simply rotating the adjustment control device.
