产品介绍：

先导式单向阀是一种先导式液控单向阀，它由

先导阀和液控单向阀两部分用可拆连接组合一

采用软硬结构，阀芯软密封面压缩量在阀座上

受限制。特别适用于需长期保压的液压系统，

体。由先导阀来控制液控单向阀的出口、控制

，使液流反向流动。为了提高密封性和确保良

好使用寿命，先导阀和液控单向阀的阀芯阀座

口断开或接通，实现利用负载压力推开单向阀

用于气压系统效果相同。

性能：

液控单向阀采用锥形阀芯，因此密封xn好。

方式有内泄式和外泄式二种。在油流反向出口

在要求封闭油路时，可用此阀作为油路的单向

锁紧而起保压作用。液控单向阀控制油的泄漏

无背压的油路中可用内泄式；否则需用外泄式

，以降控制油压力。
