对活塞锁住时的定位要求不高的场合。所示为采用液控单向顺序阀的平衡回路。当换向阀处于中位时，液控顺序阀关闭，使工作部件停止运动并能防止其因自重而下落。当换向阀左位接入后，液压油进入液压缸上腔，并进入液控顺序阀的控制口。打开顺序阀，液压缸下腔回油，背压消失，

活塞下行。因此，这种回路效率高，安全可靠，但在活塞下落时，由于自重作用使得运动部件下降过快，必然使液压缸上腔的油压降低，使液控顺序阀的开口关小，阻力增大，从而阻止活塞迅速下降。当液控顺序阀开口关小时，液压缸下腔的背压上升，

上腔油压也上升，又使液控顺序阀的开口开大。因此，液控顺序阀的开口处于不稳定状态，系统平稳性较差（严重时会出现断续运动的现象）。由上述内容可知，这种回路适用于运动部件的重量有变化，但重量不太大，停留时间较短的液压系统中。
