Claims (1)

[Scope of utility model registration request] A valve rod that adjusts the opening degree of a valve port provided between an inlet and an outlet of the body, is biased in the valve-closing direction by the elasticity of a return spring, and presses the valve body in the valve-opening direction. is connected to the valve body, and an actuator is attached to the body so that an actuating body presses the valve rod against the elasticity of the return spring in proportion to the control current, and the actuator presses the valve rod under the control of the actuator. In the proportional valve, the opening degree of the valve port is adjusted by a body, the valve port is formed to face in the vertical direction, the actuator is attached to the lower surface of the body, and the opening degree of the valve port is adjusted by the valve body. With the valve operating direction facing upward, the lower end of the plunger, which advances downward due to the elasticity of the closing compression spring, presses the valve body downward, and when energized, the plunger resists the elasticity of the compression spring. When the plunger moves backward and the lower end of the plunger moves away from the valve element, a solenoid that releases the pressure on the valve element is connected to the lower end of the guide tube of the plunger through a through hole formed in the upper surface of the body. A proportional valve with a closing function, characterized in that it is mounted on the upper surface of the body so as to face inside the body.
