磁弁。[Claims for Utility Model Registration] A valve body in which an inlet port, an outlet port, and a main valve seat provided in a passage between the two ports are formed, a diaphragm fixed to the valve body, and the diaphragm. A main valve body fixed to and seatable on the main valve seat, a pilot supply port that communicates between a diaphragm chamber formed at the back of the diaphragm and the inlet port, and a pilot supply port that communicates between the diaphragm chamber and the outlet port. A pilot discharge passage, a pilot valve body seated on a pilot valve seat provided in the pilot discharge passage, a plunger that accommodates the pilot valve body so as to be movable in the axial direction, and an electromagnetic suction movement using the plunger as a movable iron core. In the two-port solenoid valve, the main valve element is opened and closed in relation to the movement of the pilot valve element, and the pilot valve element is fixed to the main valve element, and the pilot valve element is fixed to the main valve element. The plunger is movably inserted into the plunger, and the plunger has a plunger spring tensioned between it and the valve body to apply a force toward the pilot valve body, and the pilot valve body has a pilot spring between it and the valve body. A two-port solenoid valve, characterized in that the pilot valve element and the main valve element are connected by a hang spring that is weaker than the pilot spring, and is tensioned and biased to move away from the pilot valve seat.
