The TV/HAT is a self-actuating fluid control valve ideal for use in conjunction with tracer tubing and tracing systems to keep systems warm, It is often used in winterization tracing, instrument tracing, freeze protection and other applications requiring flow temperature control. Utilizing a thermostatic wax actuator, the TV/HAT valve responds only to fluid temperature to control a system. After condensate forms and cools to the valve's set point, the valve modulates the flow to maintain a constant condensate discharge temperature. During start-up, the TV/HAT is wide open for rapid venting and initial heat-up and then will adjust based on fluid temperature. After shutdown, the valve is self-draining 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, the TV/HAT freeze protection valve maintains a constant discharge temperature, thus providing the benefits of accurate process temperature control and improved efficiency.
