Abstract

A hot gas valve has a housing, in which a gas duct is formed with an inlet and an outlet, and a valve device for controlling the fluid flow through the gas duct. The housing has at least one cooling duct for liquid cooling of the housing, wherein the gas duct is shielded with respect to the housing by means of a thermal shield, which consists of a material which has a greater thermal stability than the material of which the housing consists. The valve device has a closure body situated in the gas duct, which closure body is held on a valve shaft mounted in the housing by means of at least one bearing. The bearing may consists of a material having good thermal conductivity. The valve shaft is sealed by an elastomer shaft sealing ring on the side of the bearing facing away from the gas duct.
