Whenever hot reservoir fluid is at surface in the Flowline, the high temperature signal is transmitted through the
thermocouple connection to the Actuator Controller unit; which activates the closure of the control valve. Otherwise,
whenever there is no flow of hot reservoir fluid at surface and the flow line temperature drops, the control valve return to
its normally open position.

We need you to design and fabricate an ACTUATOR CONTROLLER to achieve this objective or if you have alternative device that can

play the same role as *SELF ACTIVATING TEMPERATURE CONTROL VALVE
