  • HDV Rectangular Single-Leaf Butterfly Valve

    ● Main components: valve body, valve leaf, shaft, bushing, 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 product 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 oiling, ensuring permanent lubrication.
    ● Used to adjust air speed and air volume, it is easy to operate, cleverly structured, and can be directly installed on the air duct.
    ● Valve color can be customized according to customer needs.
    ● WXH matches the duct size.
     
    Technical characteristics:
    1. The HDV rectangular single-leaf butterfly valve is specially designed for air volume adjustment and pressure control in ventilation and air conditioning systems.
    2. Directly installed on the air duct to adjust the indoor air volume.
    3. The adjusting mechanism is a handle type, which can be locked at any position during adjustment, and clockwise is to close the blade.
