New lotoke adopts multi-eccentric design and valve cooling design, which can better control the expansion and contraction deformation of high and low temperature. It has the advantages of high temperature resistance, light operation, no friction when opening and closing, improving the sealing performance of the butterfly valve and extending the service life. The Advantages such as

? positive circular sealing ring with spherical surface, ariants from high and low temperature. In this case, multi-offset is the best solution to the structure design of butterfly valve for high and low temperature services.
