Hydraulic pressure is generated from the second hydraulic pump 400 through the second open hydraulic line 410, 500 to the second open inner flow path 590 via the second open pump port 550. [ The hydraulic pressure having passed through the second open pilot check valve 650 passes through the open connection port 510 of the first open internal flow path 570 through the first communication point 610 and through the open connection line 511, The valve 100 is opened by the operation of the actuator 200 while being transmitted to the open hydraulic port 210 of the valve 200. The hydraulic pressure inside the actuator 200 is transmitted to the second communication point (not shown) via the closed connection port 520 of the manifold 500 along the closed connection line 521 via the closed hydraulic port 220 of the actuator 200 620 to reach the second close pilot check valve 660. [ At this time, the second close pilot check valve 660 opens the reverse flow by the second close pilot line 661, and the flow of the hydraulic pressure flows through the second close hydraulic pump port 560 to the second close hydraulic line 420, To the second hydraulic pump (400). When the second hydraulic pump 400 opens the first open pilot check valve 630 on the first open internal flow path 570 of the manifold 500 and the first open pilot check valve 630 on the second closed internal flow path 570 of the manifold 500, The first close pilot check valve 640 on the oil line 580 maintains the hydraulic pressure shutoff state because the first hydraulic pump 400 is not operated.

Figs. 13 and 14 illustrate the reverse operation of Figs. 11 and 12 and also the opening operation of the second hydraulic pump 400 and the operation of the second hydraulic pump 400 in order to close the valve 100 by the operation of the second hydraulic pump 400 It will be possible to deduce. For example, hydraulic pressure is generated from the second hydraulic pump 400 through the second closed hydraulic line 420 and flows into the second closed internal flow path 600 via the second closed pump port 560 of the manifold 500 Move. At this time, the oil pressure passing through the second close pilot check valve 660 passes through the second communication point 620, the close connection port 520 of the first close internal flow path 580 and the close connection line 521, The valve 100 is closed by the operation of the actuator 200 while being transmitted to the closed hydraulic port 220 of the valve 200. The hydraulic pressure inside the actuator 200 is transmitted through the open hydraulic port 210 of the actuator 200 to the first communication point 510 via the open connection port 510 of the manifold 500 along the open connection line 511 610 to reach the second open pilot check valve 650. At this time, the second open pilot check valve 650 opens the reverse flow by the second open pilot line 651 and the hydraulic pressure flows through the second open hydraulic line 410 through the second open pump port 550, To the second hydraulic pump (400). When the second hydraulic pump 400 is operated to close the valve 100, the first closed pilot check valve 640 on the first closed internal flow path 580 of the manifold 500, The first open pilot check valve 630 on the oil line 570 maintains the hydraulic pressure shutoff state because the first hydraulic pump 400 is not operated.
