Abstract
An improved thermally actuated valve assembly having a double throw feature comprises three ports in which two passage routes are provided through the valve; one passage route connecting ports one and two and the other passage route connecting ports two and three. A snap acting strip type bimetallic member vertically mounted in the valve serves as a thermal element and valve member to cause a change in communication from one of the passage routes to the other.
