Reverse Acting valves are designed with normally closed valve seats that open on increasing temperature. As temperature rises in the bulb, liquid in the bulb vaporizes and transmits power through the tubing to a bellows in the control valve. Heating or cooling fluid passing through the valve is thus modulated to maintain a desired temperature in the process being controlled.
