Claims

[Claims for Utility Model Registration] An electromagnetic coil is formed by a permanent magnet movable in the axial direction of the electromagnetic coil in the center hole of the electromagnetic coil, and the valve seat is located at the end of the flow path on the valve seat side. An armature provided with a valve body for opening and closing, and a magnetic material arranged in a position where the electromagnetic coil is energized and attracts the armature, and which allows the armature to be attracted by its own magnetic force even when the electromagnetic coil is de-energized. A self-holding valve unit having a fixed magnetic pole formed of and a valve seat unit having a valve seat that is opened and closed directly or indirectly by the valve body of the valve unit, and the valve unit and the valve seat unit are assembled as one body.
