A system for controlling airflow from a galley compartment (104) to a plenum chamber (108) is disclosed. The system includes an actuating assembly (200). The actuating assembly includes a cylinder (204), a heat-expanding material (208) 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 (12, 128). The valve assembly may include a louver assembly (124) coupled to the actuating assembly. The louver assembly includes a louver frame (232), one or more louver blades (236) and bracket (224) and a connecting rod that couples the actuating assembly to the valve assembly. The valve assembly may also include a poppet valve (128). The poppet valve includes a poppet body element (300), a poppet stem (308) coupled to the actuating assembly that is inserted into a channel within the poppet body element, and a poppet head (312) coupled to the poppet stem.
