Stainless steel pneumatic square damper
不锈钢气动方形风阀is a high-performance regulating device designed specifically for ventilation systems, using stainless steel material and pneumatic drive, suitable for industrial, fire smoke exhaust, and high-temperature environments. The following is its key information:
1. Core Features
Material durability: The stainless steel body is resistant to corrosion and high temperatures (such as 280 ℃ fire resistance), and can operate stably for a long time.
Pneumatic control: achieve rapid opening and closing or stepless adjustment through pneumatic actuators, adapting to the requirements of automation systems.
Square design: convenient for pipeline installation, flexible air volume adjustment, especially suitable for rectangular duct applications.
2. Typical application scenarios
Fire exhaust system: such as 70 ℃/280 ℃ fire dampers, meeting the requirements of fire safety regulations.
Industrial ventilation: used in flue and dust environments (such as metallurgy and chemical industry), supporting bidirectional medium flow.
High temperature flue gas treatment: Some models can withstand temperatures above 500 ℃ and are suitable for boilers and drying equipment.
3. Product parameters and selection
Pressure rating: from atmospheric pressure to 1.6MPa, some heavy-duty models can be customized with higher pressure.
Drive mode: Pneumatic actuator can be single/double acting, supporting flange connection (such as DN800 large-diameter model).
Customization options: Can be equipped with a worm gear manual device as a backup, or integrated with electric control.
4. Market reference
Price range: Depending on the specifications, the unit price ranges from ¥ 90 (basic manual version) to ¥ 760 (electric high-temperature version).
