A by-pass valve capable of activating a two different temperatures is disclosed. The valve has a first bore in fluid communication with a fluid inlet and a second bore having a first end in fluid communication with a first outlet and a second end in fluid communication with a second outlet. First and second branch ports interconnect the first bore and the first end of the second bore and the first bore and the second end of the second bore, respectively. A first valve mechanism is arranged in the first bore for controlling fluid flow to said first branch port and is operable at a first activation temperature. A second valve mechanism is arranged in the second bore for controlling flow to the second outlet and is operable a second activation temperature that is different than said first activation temperature, the first and second valve mechanism operating in series to provide three different operational states. |
