A mixing valve comprises a housing including first and second inlet passages and a third outlet passage. The first passage is connectable in a high temperature fluid supply line. The second passage is connectable with a low temperature fluid supply. The third passage selectively communicates with the first and second passages. A valve assembly is mounted within the housing. The valve assembly includes a thermostat element and a valve body actuatable by the thermostat element. The thermostat element is contactable thermally by the high temperature fluid passing through the first passage. The valve body is operable under the influence of the thermostat element to regulate flow of low temperature fluid and provide a mix ratio of high temperature fluid and low temperature fluid that results in a mixed fluid having a selected temperature flowing out of the third passage. The mixing valve is adapted to provide feedback to a consumer of a failure condition. |
