Valve (25) with heated sealing gas suitable for use in a regenerative thermal oxidizer (10), and oxidizer including the switching valve. The valve of the present invention exhibits excellent sealing characteristics and minimizes wear. In a preferred embodiment, the valve utilizes hot gas from the regenerative process to heat gas for sealing the valve, and sealing air flows through a heat exchanger (212) that is positioned to be in contact with hot exhaust gas from the regenerative process |
