ABSTRACT:
A fluid flow shutoff device that eliminates exposure to scalding hot water. The device includes a housing with a first and second opening for allowing fluid flow from the first to the second opening and a bimetallic element supported within the housing. When temperature of fluid flowing through the housing passes a threshold temperature, the bimetallic element changes shape causing stoppage of fluid flowing through the housing. The device further includes a flapper valve that is activated by the bimetallic element. When the element changes shape, the flapper valve is repositioned within the housing to stop fluid flow.
