  • FHF WSDc-FK Fire Damper (Rectangular)

     

    ● Main components: valve body, valve disc, shaft, bushing, fuse, inspection port, actuator.
    ● The valve body and disc are made of high-quality galvanized steel plate, featuring beautiful appearance, good corrosion resistance, and long service life.
    ● The valve assembly adopts the internationally advanced sheet metal connection technology—TOX weld-free connection process.
    ● A V-shaped anti-slip structure is designed between the disc and the rotating shaft to ensure that the disc does not slip or loosen under high wind speed.
    ● The disc rotating bearing and connecting rod rotating bearing both use oil-containing copper powder metallurgy bushings, requiring no lubrication and ensuring permanent lubrication.
    ● Normally open, in case of fire, the smoke (heat) sensor sends an electrical signal through the control center, the electromagnet in the actuator is energized, the valve automatically closes, and outputs a closed electrical signal.
    ● After the valve action, the DC motor drives the reset.
    ● The valve can be manually opened and manually reset.
    ● When the temperature rises to 70 ℃, the fuse will act, and the valve will automatically close.
    ● Action signals or reset signals are fed back to the control center and start interlocking devices.
    ● When W≥1250, an intermediate frame is added, and the blades are separated.
    ● When H≥1500, 2 actuators are installed.
