     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.

Cast Iron Chain H78A/H78B

    Characteristic

    1 Convenience sluicegate rapidly, fluid resistance small, labor saving, can often operate.

    2 Has the advantages of simple structure, small volume, light weight.

   3 To transport slurry, accumulation of fluid in the pipe outlet at least.

   4 The low pressure, can achieve a good seal.

   5 Good regulation performance.
