とする電磁弁装置。In an electromagnetic valve device configured to open and close a valve body by controlling energization to an excitation coil, a piston that slides in a cylinder facing the back of the valve body is formed integrally with the valve body, forming a pressure balance passage inside the valve body that communicates a back pressure chamber formed by the cylinder and the piston with a passage upstream from the seat portion of the valve body;
The opening direction of at least one opening on the seat side in the pressure balance passage is made substantially perpendicular to the direction of fluid flow around the valve body, and the tip of the valve body in which the opening is formed is 1. A solenoid valve device, characterized in that a flow guide that covers the opening in a non-contact manner is installed in a passageway upstream of the opening.
