Product Description

D373H hard seal butterfly valve adopts three-dimensional eccentric oblique conical valve seat seal, butterfly plate seal adopts new metal sheet and elastic material laminated, embedded in the butterfly plate and valve seat. The use of butterfly plate swing compression tight seal, so the sealing surface friction resistance is small, closed with the tighter function, so reliable sealing, open to ensure that the sealing surface is completely out of contact, to ensure that the sealing surface is not damaged. The structural characteristics of the butterfly valve exclude the shortcomings of other types of butterfly valves that can not be sealed by opening too much, and can be used normally under high dawn, overcoming the shortcomings of other types of valves that are easy to leak due to thermal expansion when used at high temperature. The butterfly valve cultivator use medium requirements, the selection of different sealing surface materials, to ensure that the sealing surface wear resistance, corrosion resistance, long service life.
