Utilizing a thermostatic wax actuator, the TV/HAT (Tube Valve/Heat Actuated Trap) freeze protection 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.
TV/HAT valves are ideal for use in conjunction with tracer tubing and tracing systems using pre-traced tubing bundles. These valves are optimal 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.
