| Product description: |
The scope of application and the principle: Applicable to the ventilation, air-conditioning duct with flow volume control and fire prevention demand. Usually the damper is open. When fire occurs, the fuse plug promptly close automatically. Manually open the damper to reset the system
1. Close the valve manually 2. Close the valve automatically when fuse plug reaches its fusing temperature 70°C. 3. Adjusting air flow volume at will between 0°- 90° 4. Biggish circular fire damper uses rectangular damper body equipped with a circular angle iron flange. 5. Can install additional signal device as users demand. |
| Specification: | Standard Size: 300*300 also can be made according to your request |
(l) The air supply aluminum grille damper is unified in four sizes for the blade width, the blade shape is a diamond-shaped double blade, and soft laps are used between the blades, so the hermeticity is good.
(2) Air flow control valve body frame is cold-rolled with 2 mm galvanized sheet and then welded with carbon dioxide gas or welded by ordinary Q235 plate; the blade is cold-rolled with 1 mm galvanized sheet into corrugated shape, two pieces Synthetic spot welding insert square shaft, or 2 mm G235 steel plate cold forming, single piece punching insert square shaft or welding round shaft.
(3) The regulating valve is divided into manual and electric, and it is divided into four types according to the used materials: iron plate, galvanized plate, aluminum alloy plate and stainless steel plate. The valve body structure and size are the same.
Widely used in industrial and mining, civil buildings, HVAC systems, and the precise adjustment of air flow is one of the key equipments for controlling ventilation modes in various environments. Its main features are flexible operation, low noise, small leakage, (closed leakage <0.5%), wide working temperature range, reliable structure, and safety and convenience.
