    ● 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 process.
    ● 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, when the air temperature in the pipeline reaches 70℃, the fuse will act and the valve will automatically close.
    ● The valve can be manually opened and closed, and manually reset after the valve action.
    ● The valve has six airflow opening levels.
    ● Can output valve closing signal.
    ● When W≥1250, add an intermediate frame and separate the blades.
    ● When H≥1500, install 2 actuators.
