Fire protection dampers are crucial components within the ventilation and air-conditioning systems, designed to ensure optimal safety and efficiency. These state-of-the-art dampers remain open under normal conditions. However, in the event of a fire, when the gas temperature in the pipeline climbs to 70°C, they autonomously close to form a robust smoke barrier. Not only do they meet stringent requirements for smoke leakage and fire resistance, but they also maintain integrity for prolonged periods. Exhaust dampers, typically installed at the suction entrance of exhaust fans or along the exhaust system pipes, are generally kept closed to prevent air leakage. In case of fire or when smoke exhaust is necessary, these dampers can be manually or electrically opened to facilitate efficient smoke evacuation. The fire valve is predominantly located in the air ducts of ventilation and air conditioning systems, while the smoke exhaust fire valve is usually found in the ducts of smoke exhaust systems.
