A system for controlling airflow from a galley compartment to a plenum chamber is disclosed. The system includes an actuating assembly. The actuating assembly includes a cylinder, a heat-expanding material disposed in the cylinder, and a piston disposed in the cylinder, wherein the heat-expanding material is configured to actuate the piston when the heat-expanding material is heated. The system includes a valve assembly. The valve assembly may include a louver assembly coupled to the actuating assembly. The louver assembly includes a louver frame, one or more louver blades and bracket and a connecting rod that couples the actuating assembly to the valve assembly. The valve assembly may also include a poppet valve. The poppet valve includes a poppet body element, a poppet stem coupled to the actuating assembly that is inserted into a channel within the poppet body element, and a poppet head coupled to the poppet stem.
