する閉止機能付比例弁。 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. The proportional valve is configured to adjust the opening degree of the valve port by a body, and the proportional valve has a built-in closing compression spring that biases the valve body in a valve closing direction, and a plunger elastically contracts the compression spring when energized. The solenoid for releasing the bias is attached to the body by fitting the tip of the guide tube of the plunger into a through hole formed in the body, and the solenoid is attached to the body between the circumference of the guide tube and the through hole, and A proportional valve with a closing function, characterized in that a seal member seals between the inner periphery of the guide tube and a core fitted into the guide tube.
