Operation

TV/HAT valve responds only to temperature. After condensate forms and cools to near the set point, the TV/HAT valve modulates the flow to maintain a constant condensate discharge temperature. TV/HAT valves are wide open at start-up for rapid venting and initial heat-up. TV/HAT valves 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 benefits of accurate process temperature control and improved efficiency.

Applications

TV/HAT valves are ideal for use in conjunction with tracer tubing and tracing systems using pre-traced tubing bundles. TV/HAT valves are ideal for replacing conventional steam traps on winterization tracing, instrument tracing, condensate return system freeze protection, tracing for processes under 150°F (65°C), and other applications requiring in-line flow control based on temperature.
