<p>A directional control valve device is provided with a first control valve (11) which is switched between a first supply position (X1) and a first discharge position (Y1), and a second control valve (12) which is switched between a second discharge position (Y2) and a second supply position (X2). The directional control valve device is configured to allow the first control valve (11) of a first control mechanism (21) to switch to the first supply position (X1) when a second control mechanism (22) switches the second control valve (12) to the second discharge position (Y2). A check valve (31, 32) is provided on at least one among the inside of the first control valve (11) in the first supply position (X1), and the space between the pressure port (P) and the first control valve (11). The pressure fluid supplied to the second control valve (12) in the second supply position (X2) switches the first control valve (11) to the first discharge position (Y1) via the first control mechanism (21) when the second control mechanism (22) switches the second control valve (12) to the second supply position (X2).</p> |
