Abstract
This valve device is provided with: a body () that has at least one passage () for passing a fluid and valve shaft holes (); a valve shaft (), which is passed through the valve shaft holes so as to be rotatable; and butterfly valves (), which are fixed on the valve shaft and are for opening and closing the passages (). The butterfly valves () are disposed so as to close the passages () on a downstream side or an upstream side of the valve shaft holes () in a flow direction of the fluid. As a result, it is possible to prevent fluid leakage and achieve effective utilization of exhaust heat in an exhaust heat recovery system.
