Zusammenfassung:A valve device is provided, by which a reverse flow can be avoided without being restricted by pipe arrangement and without bending a primary piping, thereby preventing a defective operation due to a dynamic pressure from occurring. An inlet side inner passage includes a bent part (formed with an inlet side lateral inner passage 21 and the inlet side longitudinal inner passage 22 ) in a valve housing 11 , that is, the inner passage formed in the valve housing 11 takes charge of such a bent part required in a primary piping to avoid a reverse flow.
