Our advanced Fire Protection Damper is engineered for optimum safety and reliability! With a 70 fusible piece that activates closure, the valve seamlessly closes either by its own weight or can be manually reset with a spring pull. For those with specialized needs, users have the option to integrate an output signal device, ensuring the damper meets any unique requirements.
The fire valve, normally open, is installed in the supply and return air circulation system of the ventilation and air conditioning system. When the gas temperature in the pipeline reaches 70 °C or 280 °C in a fire, the fusible sheet will be cut off and the valve will automatically close under the action of the torsion spring force. It can meet the requirements of fire stability and fire integrity in a certain period of time, and play the role of fire barrier. When the valve is closed, it will output a closing signal.
1. Automatic Closure Upon Temperature Control: Ensures immediate action during emergencies. 2. Manual Closure: Provides flexibility for maintenance or specific scenarios. 3. Manual Reset: Offers ease of resetting post-activation. 4. Shut Down Contact Signals: Outputs a group of contact signals for comprehensive safety management. 5. Versatile Duct Compatibility: For round air ducts with diameters greater than or equal to 630mm, select either a square or circular fire damper to fit your needs.
