  • Product Description
  • Technical parameters

  • Performance ：

    1、 Normally in the open state, in case of fire, the smoke (temperature) sensor sends an electrical signal (DC24V) to the control center, the electromagnet in the actuator is energized, the valve automatically closes, and outputs a closed electrical signal.

    2、 The valve can be manually closed or closed at 70℃ by the temperature sensor.

    3、 The valve has six manual adjustments for air volume opening.

    4、 Manual reset after valve operation.

     

    Structure ：

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

    Maximum valve size: 1250×800

    The actuator torsion spring torque can be adjusted in three stages.

    Matching actuator model: JFHF WSDc-FK 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.

     

    Conditions of Use ：

    Static Pressure: 1500Pa or less

    Maximum air velocity: 15m/s

    Ambient operating temperature: -10℃ ~50℃

    Ambient operating humidity: Relative humidity 85% or less

     

    Precautions

    1. Users should not paint on the outside of the actuator, and should not add oil to the electrical components, which 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 sensor should be performed every six months during normal use.
