The shell thickness of the valve shall not be less than 2mm. Easy to melt components shall comply with fire department approval standards.
3. selection of smoke fire valve should pay attention to the function of the valve, normally open or normally closed, automatic shutdown, open, manual closed, open, manual reset, signal output, remote control requirements.
4. smoke dampers are suitable for ventilation, air conditioning, or smoke extraction systems
5. smoke fire dampers for ventilation and air conditioning system, in addition to public buildings kitchen smoke exhaust system with fire dampers, action temperature of 150 degrees outside, general ventilation and air conditioning system with smoke exhaust fire valve action temperature of 70 degrees.
6. if the smoke damper and the fan linkage should be selected with dual micro switch device.
