  • Product Description
  • Technical parameters

  • Performance ：

    1、 Normally open, when the airflow temperature in the pipe reaches 700 C, the temperature sensor activates, and the valve automatically closes.

    2、 The valve can be manually opened and closed, and manually reset after the valve action.

    3、 The valve has six manual adjustment levels for airflow volume.

    4、 Can output valve closing signal.

     

    Structure ：

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

    Maximum valve size: 1250*800

     

    Matching actuator model: JFHF WS-FK-1

    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 critical for life safety and must be installed and commissioned by professionals. Regular checks of opening, closing, electrical signal operation, and temperature sensor should be performed every six months during normal use.
