1,In the conventional butterfly valve, the valve inside and valve plate are lined with PTFE, so that the media and the valve body are isolated, to achieve the effect of corrosion.
2, Under the conventional conditions, BT410 can replace the stainless steel valve, with a higher performance/price ratio. The butterfly plate of valve is installed in the direction of the diameter of the pipe.
3,In the well-known butterfly valve technology, the way to seal mostly uses sealing structure and the material to seal is PTFE and so on. Due to the restrictions of structural characteristics, it cannot adapt to high temperature, high pressure and corrosion resistance, wear resistance and other industries.
