By opening and closing the pilot hole with a solenoid valve, the pressure in the pressure regulating chamber changes and the pressure-operated valve is displaced, thereby increasing the pressure between the high-pressure side pipe and the low-pressure side pipe. In the pilot type solenoid valve which is opened and closed, the pressure is actuated in the direction of opening between the two pipelines in order to adjust the flow rate of the fluid flowing from the high pressure side pipeline to the low pressure side pipeline. A pilot type solenoid valve characterized by being provided with a variable stopper that allows the maximum displacement of the valve to be adjusted from the outside.
