徴とする比例制御電磁弁。A core fixed to the axis of a bottomed cylindrical frame made of a magnetic material, a coil wound around the outer periphery of the core, and a magnetic compensator placed at the bottom of the bottomed cylindrical frame. a plate, a magnetic plate fitted into the opening side of the bottomed cylindrical frame, a valve body attached to the opening side of the bottomed cylindrical frame of the core so as to be movable in the axial direction; It has a valve seat that is disposed at a position facing the valve body and cooperates with the valve body to open and close a fluid flow path, and a spring that presses the valve body against the valve seat. A movable core made of a magnetic material on the core side and a flexible permanent magnet on the lower side of the valve seat are coupled together, the valve seat is made of a flexible permanent magnet, and both the permanent magnets of the valve body and the valve seat are made of a flexible permanent magnet. The opposing surface is a proportional control solenoid valve characterized by the ability to grow magnetic poles in opposite directions.
