Disclosed is a dual-cylinder de-activation (CDA) device including a body; a swing arm connected to one side of the body and brought into contact with a cam by rotation of the cam to rotate with respect to the body; a latching part connected to the other side of the body to move between an unlocking position where the swing arm rotates with respect to the body, and a locking position where it is engaged with the swing arm to restrict rotation thereof with respect to the body, the latching part being connected to a pivot part capable of supplying an operating fluid to move between the locking position and the unlocking position; and a plurality of stem contact members provided with the valves at one side of the body which is connected to the swing arm to support the valves. The valves are connected to or supported by one CDA device, and are stably supported by one CDA device, thereby increasing the utilization of the space including the cylinder. |
