In a directional control valve with a manual operation device, the manual operation device is installed between the drive chamber side of the main valve and the pilot valve, and the above-mentioned The drive chamber and the input and output passages of the pilot valve are opened, and an operating rod airtightly inserted into the valve chamber is pressed downward to cause the drive chamber to communicate with one of the passages and to communicate with the other passage. A directional control valve with a manual operation device, characterized in that it is provided with a manual valve body that cuts off communication between the two.
