In the realm of building safety, Automatic Fire Dampers and Smoke Exhaust Valves stand as critical guardians, meticulously engineered to combat the spread of destructive fire and insidious smoke during emergencies. Automatic Fire Dampers automatically engage to seal off areas when signaled by a fire alarm or heat detector. Expertly integrated within HVAC ducts, they serve as stalwart barriers, halting the advance of fire and smoke from one zone to another. Compliance with stringent building codes necessitates regular testing and inspection to ensure these dampers remain vigilant in their performance. Meanwhile, Smoke Exhaust Valves are strategically placed to actively draw out smoke, safeguarding critical escape routes and essential areas, thus facilitating unimpeded evacuation and efficient firefighting efforts. These valves are orchestrated by a sophisticated control system that responds to rising smoke levels, ensuring optimal safety for occupants. The synergy between Automatic Fire Dampers and Smoke Exhaust Valves forms an indispensable defense mechanism, crucial for protecting lives and infrastructure from the perils of fire and smoke. Regular installation, maintenance, and testing are imperative to ensure these systems are poised for action whenever the need arises.
Usually open, the Angle of the blade can be manually adjusted in the range of 0 degrees to 90 degrees, in the event of a fire, the gas temperature of the pipe reaches 70 degrees, then the fuse protector will be blown, and the damper will be closed under the pull of the spring. Compared with ordinary fire damper, it can also be opened and closed by DC24V electrical control.

It is suitable for the air duct of ventilation and air conditioning system with smoke and fire prevention requirements, especially for important buildings that cannot be manually reset.
Fire dampers diversify into a spectrum of structural forms, each tailored to specific functions: smoke exhaust valves, smoke exhaust fire dampers, fire control valves, and combined smoke and fire control valves. Smoke Exhaust Valves, strategically installed along high-rise and underground smoke exhaust systems, feature capabilities like temperature-triggered electrical signal linkage, simultaneous activation with smoke exhaust fans, manual operation with concurrent fan initiation, and output of valve position signals. Smoke Exhaust Fire Dampers are pivotal in systems demanding both smoke evacuation and fire prevention, executing a fail-safe closure at temperatures exceeding 280, accompanied by smoke exhaust fan cessation. Fire-Proof Regulating Valves, designated for ventilation and air-conditioning networks with fire-proof stipulations, activate at 70, halting airflow and broadcasting valve closure signals, with adjustable air volume modulation. Smoke and Fire-Proof Regulating Valves cater to systems requiring dual protection, employing smoke or temperature-activated electronic signal linkage for valve closure and fan deactivation, manual closure functionality, and a 70 temperature fuse for fail-safe operations with incremental air volume regulation across a 90° span in five equal stages.
