ABSTRACT:
A regulating valve having a fail-safe action which is suitable for controlling the flow of either a heating or cooling medium in response to a sensed condition is disclosed. The flow of heating or cooling medium is responsive to changes in temperature at a selected location, which changes are sensed by thermal element. The fail-safe action of the regulating valve either permits or prevents flow of the heating or cooling medium upon failure of the thermal element.
