  • Product Description
  • Technical parameters

  • Performance ：

    1、 Normally open, it cuts off power or gas source in case of fire, the valve automatically closes, and outputs a closing electrical signal.

    2、 The valve can be manually closed or closed by ℃ temperature sensor.

    3、  After the valve action, the temperature sensor is not damaged, and it automatically resets after power and gas are restored.

    4、 It can be remotely closed electrically.

     

    Structure ：

    Main components: valve body, blade, shaft, bushing, temperature sensor, actuator, stainless steel spring plate, torsion spring, etc.

    W direction plus intermediate frame, blade separation

    Maximum valve size: 1250*800

    W×H matches the duct size, and the flange size is the same as the flange of the metal rectangular duct in national standard GB50234-2002.

    Precautions

    1. Users should not paint the outside of the actuator during use, and should not add oil to the electrical components, as this may cause malfunctions.

    2. Fire dampers are related to life safety and must be installed and debugged by professionals. Regular checks of opening, closing, electrical signal operation, and temperature sensors should be performed every six months during normal use.
