Abstract
A butterfly valve for handling materials where the temperature of the materials flowing through the butterfly valve can exceed the breakdown temperature of the sealing member with the butterfly valve inhibiting contact of hot transportable materials with the sealing member to isolate the hot transportable materials from the sealing member. Cooling conduits maintain at least portions of the valve that contacts the sealing member at a temperature below the breakdown temperature of the sealing member to prevent seal failure.
