Usually it is open, the angle of blade is adjustable at the range of 0 degree to 90 degrees manually, once fire occurs, the gas temperature of duct arrives at 70 degrees, and then the fuse protector will be fused and the damper will close under the pull of spring. Compared with the ordinary fire proof damper, it also can be opened and closed by DC24V electrical control.

Application of Damper butterfly air vent valve:

Apply to air ducts of ventilation and air-conditioning system which has smokeproofing and fireproofing requirements, especially suitable for the important buildings that can not be reset manually.

Features of Damper butterfly air vent valve:

l Using galvanized steel as material to make sure good insulation performance, fire & corrosion resistance.

l Duration, long service life.

l Easy installation.

l The flange is bended directly by the frame.

l The valve size and color can be customized according to customer's requirements.

l By DC24V power to close the valve

Advantages of Damper butterfly air vent valve:

l Excellent quality control processes, all products have been inspected strictly.

l The quality of products has reached the standard of “Code of acceptance for construction quality of ventilation and air conditioning works" (GB50243-2002) and "Fire dampers for building venting and smoke-venting system" (GB15930 2007).

l Complete accessories production and distribution make it easier to install.
