手动换向阀
A cartridge-style manual 4-way，
pull-to-shift，directional valve.
四通手动换向阀
SYMBOL
In its steady-state, spring-offset position, the valve directs flow from ③ to ② , and from
④ to ① . In the actuated (pulled) position, the cartridge directs flow from ③ to ④ ,and
from ② to ① . The spring chamber is vented at ① .
Note: Pressure at port ① will directly act on the spool and spring. Port ① is
intended to be a tank port only. Series operation is prohibited due to the tank port
① pressure rating.
A unique pull-and-rotate feature for holding the positive actuated position is optional.
A 90
°
rotation is required to position at the hold slot. The valve resets to spring-return
de-actuated with a slight pull and a 90
°
turn from the locked actuated position.
在初始时，弹簧复位，此阀允许油液从③流向②，然后从④流向 ①。在接通 ( 拉开 )
位置时，油液从③流向④，然后从②流向①。弹簧室泄油孔接通①。
注：油口①的压力将直接作用在阀芯和弹簧上。油口 ① 只作为油箱接口。可以采用独
特的拉动旋转功能来保持接通阀位。要在固定槽内定位，需要将手柄旋转 90
°
。轻轻
拉动手柄并从锁定阀位旋转 90
°
后，弹簧复位，油液通道关闭。由于油箱油口①的额
定压力，因此禁止串联使用。
