A heater control valve comprising: a valve body defining a chamber and a bypass passage extending therefrom. A first conduit in fluid communication with the bypass passage for defining a first inlet port and a first exit port adapted to communicate coolant to an external device. A flexible divertor mounted in the bypass passage and extending into the first conduit for diverting fluid into the bypass passage as a function of flow rate. A second conduit, in communication with the chamber defining a second inlet adapted to receive flow from the external device and a second outlet. The valve body further including a first seating surface disposed about an upstream end of the bypass passage and a second seating surface disposed about the second inlet, and a bypass valve, rotatable from a first position in sealing engagement with the first seating surface to a second position in sealing engagement with the second seating surface, and an actuator, for rotating the bypass valve from the first position to the second position in response to control signals.
