  • FHF WSDj-FYK Fire Damper

     

    ● Main components: valve body, valve disc, shaft, bushing, fuse, inspection port, actuator.
    ● The valve body and blades are all made of high-quality galvanized steel plate, with the advantages of beautiful appearance, good corrosion resistance, and long service life.
    ● The valve combination adopts the internationally advanced sheet metal connection technology - TOX weld-free connection technology.
    ● A V-shaped anti-slip structure is designed between the blade and the rotating shaft to ensure that the blade does not slip or loosen under high wind speed.
    ● The blade 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 (temperature) sensor sends an electrical signal through the control center, the electromagnet in the actuator is energized, the valve automatically closes, and outputs a closing 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, add an intermediate frame and separate the blades.
    ● When H≥1500, install 2 actuators.
