Abstract
A valve apparatus having a first housing coupled to a second housing. The first housing having a first chamber in fluid communication with a first inlet and a first outlet. The first chamber adapted for receiving a thermal actuator moveable from a first position to a second position in response to temperature of a first fluid in the first chamber. The second housing having a second chamber in fluid communication with a first and a second ports, the second chamber being fluidly sealed from the first chamber. The second chamber adapted for receiving a valve mechanism, which is operatively coupled to the thermal actuator and moveable from a first valve position preventing flow of a second fluid from the first port to the second port to a second valve position permitting flow of the second fluid from the first port to the second port upon actuation by the thermal actuator.
