Fire damper
Fuse the 70°C fuse, close the valve by its own weight, or pull the spring manually reset (if the user has special requirements, you can add an output signal device).
1. The temperature control is automatically turned off
2. Close it manually
3. Reset it manually
4. Shutdown output a set of contact signals
5. When the size of the circular air duct is greater than or equal to 630mm, choose square/circular fire damper
Fire dampers are categorized by their specialized functions: smoke exhaust valves, smoke exhaust fire dampers, fire control valves, and smoke and fire control valves. Smoke exhaust valves, integral to high-rise and underground building systems, offer seamless integration with temperature and smoke electrical signals, synchronizing with the smoke exhaust fan's operation. They enable manual valve activation, automatically triggering the fan, and provide real-time valve opening signals. Smoke exhaust fire dampers cater to systems requiring both smoke extraction and fire prevention, automatically closing upon reaching 280, thus halting fan operation. Fire-proof regulating valves, installed in ventilation pipelines with fire-proof prerequisites, react at 70 to close valves, sending signals to stop fan operation, and permit stepless air volume control. Smoke and fire-proof regulating valves, vital for systems with stringent smoke and fire-proof demands, leverage signal linkages to close valves and cease fan functions manually or automatically at 70, offering precise air volume adjustment in five equal 90° increments.
