The Application and principle of ventilation butterfly valve

       Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. 

     Our products are used in many different industry sector, like in automation engineering, drive engineering, conveyor technology, assembly and handling technology,transmission chain， lifting chain，belt guides，packaging industries, the beverage, food and medical engineering, pharmaceutical production, and laboratory equipment.

      Butterfly valve is a valve with a simple structure, but also can be used for low pressure pipeline medium control switch.

    Ventilation butterfly valve is a non sealed butterfly valve.

   Ventilation butterfly valve used in chemical industry, building materials, power plant, glass and other industries in the ventilation,environmental protection dust cold or hot air in the gas pipeline, as the gas medium flow adjustment or cut off the pipeline control device. This type valve should normally be installed horizontally in the pipeline.

    Main products: large ventilation butterfly valve, electric butterfly,leakage rate of 0, explosion-proof ventilation butterfly valve.

    Use

    Ventilation butterfly valve is a non sealed butterfly valve, widely used in building material, metallurgy, mine, electric powerproduction process medium temperature ≤ 300 ℃ nominal pressure 0.1Mpa pipe, used to connect, open and close or adjust the medium quality.

    Working principle

    Ventilation butterfly valve is divided into manual and electric drive,or turbine driven by motor drive, the disc rotate freely to hoist orregulating media flow in the range of 90 deg.
