  • Product Description
  • Technical parameters

  • Performance ：

    1、 Normally closed during normal operation. In case of fire, the smoke (temperature) sensor sends an electrical signal ( DC24V) to the control center, energizing the electromagnet in the actuator, automatically opening the valve and outputting an opening electrical signal.

    2、 The valve can be opened manually.

    3、  Manual reset after valve operation.

    Structure ：

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

    W direction with intermediate frame, blade separation

    Maximum valve size: 1250*800

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

     

    Matching actuator model: JPYF SDc-K

    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: Below 1500Pa

    Maximum air velocity: 15 m/s

    Ambient operating temperature: -10℃~50℃

    Ambient operating humidity: Relative humidity Below 85%

  •  

    Main Technical Parameters ：

    Microswitch Contact Capacity: AC220V 3A

    Rotation Direction: Counterclockwise opening when activated

    Action Time: Instantaneous

     

    Circuit Diagram ：

    Red wire :DC24V “+” terminal

    Blue wire :DC24V “-” terminal

    Yellow wire :Signal line

     

    Precautions

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