Abstract

A thermally actuated valve is provided herein. The thermally actuated valve includes a valve fitting, a valve body, and a movement control mechanism. The valve fitting includes an active member to selectively activate based on an input. The valve body includes a passive wax member that moves between a passive contraction state and a passive expansion state based on a passive temperature. The movement control mechanism is disposed between the valve fitting and the valve body. The movement control mechanism controls movement of the valve body between an open state and a dosed state based on movement of at least one of the active member and the passive wax member.
