バルブにおいて、共通ブロツクに、ひとつの制御
系を操作した時に発生する圧力のうち高い方を選
択するシヤトル弁と、いまひとつの制御系を操作
した時に発生する圧力のうち高い方を選択するシ
ヤトル弁と、それらシヤトル弁で選択された圧力
を比較して回路最高圧力を選択しその圧力信号を
コントロールバルブ内に導くシヤトル弁を配設し
たことを特徴とするシヤトルバルブ装置。 In a control valve that controls multiple actuators, the common block includes a shuttle valve that selects the higher of the pressures generated when one control system is operated, and a shuttle valve that selects the higher of the pressures that occur when the other control system is operated. A shuttle valve device is provided with a shuttle valve that selects one of the two modes, and a shuttle valve that compares the pressures selected by the shuttle valves, selects the highest pressure in the circuit, and guides the pressure signal into the control valve.
