Claims (1)
ス通路を開閉するヤング溝と一対のシリンダ圧通路を交
互に開閉する１対の溝とを有するスプールを具えたシリ
ンダの制御弁において、前記スプールに摺動自在に付設
され前記センタバイパス通路の圧力ポート側からバネ付
勢に抗したパイロット圧が付加されて前記パイロット圧
の低圧時に前記シリンダ圧通路の一方を閉鎖するバルブ
を設けたことを特徴とするシリンダの制御弁。In the cylinder control valve, the cylinder control valve includes a spool that is slidably inserted into the valve body and has a Young groove for opening and closing a center bypass passage, and a pair of grooves for alternately opening and closing a pair of cylinder pressure passages. A valve is provided that is slidably attached to the spool and that applies pilot pressure against the spring bias from the pressure port side of the center bypass passage to close one of the cylinder pressure passages when the pilot pressure is low. Characteristic cylinder control valve.
