TV/HAT valves respond only to temperature. After condensate forms and cools to near the set point, the valve modulates the flow to maintain a constant condensate discharge temperature. The valves are wide open at start-up for rapid venting and initial heat-up and are self-draining after shutdown, to eliminate freeze damage. For heating of temperature-sensitive instruments or process fluids, the reduced temperature available for tracing simplifies operations and eliminates overheating problems. For other heat transfer fluids, TV/HAT valves maintain a constant discharge temperature, thus providing the benefits of accurate process temperature control and improved efficiency.
