lug butterfly valve products overview:

 
The valve adopts three-dimensional eccentric conical seat seal. The butterfly plate seal is laminated with a new type of metal sheet and elastic material, which is embedded on the butterfly plate and coincides with the valve seat. The butterfly plate is used to swing and compress the seal, so the friction resistance of the sealing surface is small, and the more close the sealing surface is, the closer the sealing is, the more reliable the sealing performance is. The sealing surface is completely separated from the contact by opening, and the sealing surface is not damaged.
 
The structure of the butterfly valve eliminates the shortcomings of other types of butterfly valves that can not be sealed due to over opening, and can be used normally under high temperature, which overcomes the defect of easy leakage of other types of valves due to thermal expansion in high temperature. According to the requirements of service medium, the butterfly valve selects different sealing surface materials to ensure wear resistance, corrosion resistance and long service life of the sealing surface.
