Abstract
A valve device has a main body in which an exhaust hole configuring a part of the gas drainage path is formed; a valve element capable of opening and closing the exhaust hole; a cylinder housing a piston coupled to the valve element; and an electromagnetic selector valve for selectively switching a supply route of a driving fluid supplied from a fluid supply source of a die-casting machine to the cylinder either to a front chamber of the cylinder or to a rear chamber of the cylinder. The main body includes a front face configuring a part of a parting face and a fitting portion that tightly adheres to a wall face of a housing hole. The electromagnetic selector valve is positioned on a rear side of the main body, and positioned inwardly of a contour line of the man body formed by the fitting portion.
