Fire damper Installed on the supply and return air ducts of ventilation and air conditioning systems, this valve remains open during normal operation. In the event of a fire, when the gas temperature inside the pipes reaches 70°C, the fusible link melts, causing the valve to close automatically under the force of the torsion spring. It can meet the requirements for fire resistance stability and integrity for a certain period of time, serving as a smoke and fire barrier. When the valve is closed, it outputs a shutdown signal. Dust Removal and Fire Prevention Valve Mounted on the exhaust system piping, typically in a closed state during normal operation. Manually or electrically activated in case of a fire to facilitate smoke extraction. Closes when the smoke pipe temperature reaches 280°C, meeting fire resistance stability and integrity requirements for a certain period, serving as a smoke extraction valve. Product Principle Installed in the central air conditioning duct system, it operates on the principle of temperature control using fusible alloys. It closes the valve with the aid of gravity and a spring mechanism. In the event of a fire, as flames enter the duct, the high temperature melts the fusible alloy on the valve or causes the shape-memory alloy to deform, automatically closing the valve. It is used in situations where the duct passes through fire-resistant divisions.
