Products design features

 

The series of the butterfly valves can be applied to food,drink,medicine,chemical industry,industrial environmental protection water treatment,high building,water supply, drainage and gas, etc.used to start or stop or adjust medium flow quantity,The major features of the structure.

1. Simple structure,small volume,light weight,small installation dimension.

2. Having two kinds of seal material: soft and hard,can be used in various working conditions,with good sealing performance, and long life-span.

3. Anti-fire structure designed butterfly valve can prevent the expanding of an accidental fire,once the soft sealing valve seat of the butterfly valve catches fire and damaged,the stainless steel seal ring will give play to make butterfly valve keep emergency sealed.

4. In the condition of the butterfly valve fully opened,it has little flow resistance,and in the condition of the butterfly valve partially opened,the flow quantity can be controlled sensitively.

5. Little driving couple,convenient and quick operations.
