PROBLEM TO BE SOLVED: To simplify a hydraulic circuit by providing a first valve and a second valve arranged in series in the same hole part formed in a valve body to make the same oil pressure act in opposing end parts, respectively. SOLUTION: A plug for a control valve has the valve body, the first and second valves which are arranged in series in the same hole part formed in the valve body and in which the same oil pressure acts in opposing end parts, respectively, and a pin arranged so as to function as a stopper between the first and second valves. Moreover, it has the valve body, the first and second valves which are arranged in series in the same hole part formed in the valve body and in which the same oil pressure acts in opposing end parts, respectively, a plug arranged between the first and second valves so as to function as a stopper, and a communicating hole part provided so as to communicate a first valve side with a second valve side in the plug. |
