  • PYF SDc-K Smoke Exhaust Valve

     

    ● Main components: valve body, valve blade, shaft, bushing, 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 closed, in case of fire, the smoke sensor sends an electrical signal through the control center, the electromagnet in the actuator is energized, the valve opens automatically, and outputs an opening electrical signal.
    ● The valve can be opened manually.
    ● Manual reset after valve operation.
    ● When W≥1250, add an intermediate frame and separate the blades.
    ● When H≥1500, install 2 actuators.
