御弁。 A valve element for adjusting the opening degree of the valve opening is provided on the outlet side of the valve opening provided between the inlet and the outlet of the body, and the valve element is biased in the valve closing direction by the elasticity of a return spring. and an actuator that connects a valve rod that presses the valve body in the valve-opening direction to the valve body, and that causes an operating body to press the valve stem against the elasticity of the return spring in proportion to the control current. In the proportional control valve, which is attached to the body and is configured to adjust the degree of opening of the valve port by the valve body by controlling the actuator, the elasticity of the return spring can be adjusted, and the elasticity of the return spring is adjustable. A biasing spring biasing toward the valve is provided, and when the actuator is not energized, the sum of the elasticity of the biasing spring and the fluid pressure on the inlet side, the elasticity of the return spring, and the fluid pressure on the outlet side. 1. A proportional control valve characterized in that the valve port is opened to a constant opening degree in balance with the sum of fluid pressures.
