Claims

[Claims for Utility Model Registration] 1. A valve body having a valve seat, a valve body that engages with the valve seat,
Two cylindrical electromagnetic coils are arranged in a diaphragm attached to the valve body and a cylindrical yoke made of a soft magnetic material attached to the valve body so that the same polarity occurs in adjacent parts. and a movable element having a permanent magnet magnetized so as to interlink with each different pole of each of the cylindrical electromagnetic coils in the center of the electromagnetic coil, and an inner circumferential surface of the cylindrical electromagnetic coil. A non-magnetic spherical body is provided in a space in which the movable element is interposed so as to be movable in the axial direction, and a reciprocating drive device is provided in which a shaft is provided at one end of the movable element, and the shaft is moved through the diaphragm to move the movable element in the axial direction. A gas proportional control valve, characterized in that the valve body is connected to a valve body, and the valve body is supported by the valve body via an elastic member. 2. The gas proportional control valve according to claim 1, which is characterized by having a structure in which the elastic force of the elastic member can be adjusted from outside the valve body.
