2S型液控单向阀：
1、用于垂直叠加安装；
2、按需要可以无泄漏封闭一个或两个工作油口。
说明：
1、Z2S型阀是叠加式结构的液控单向阀。
2、即使长时间的保压，一个或两个的工作油口仍保持无泄漏的密封。
3、由A至A1或由B至B1是自由流通的，而反方向则封闭。
4、如油从B流经阀至B1，压力作用在活塞上。活塞便向左运动，将锥阀芯推离其阀座。此时油便可从A1流向A。
5、为保证锥阀芯正确闭合，当控制阀处于时，阀的工作油口与油箱想通。

        注意事项
1、液压系统用的介质必须过滤；过滤精度至少20μm。
2、液压系统用的油箱必须密封；并加空气过滤器。
3、华德产品出厂时不带底板。（如需用请订货）。
4、固定螺栓请按样本中列的参数选用。
5、与阀连接的表面粗糙度要求0.8R。
6、与阀连接的平面度要求0.01/100mm。
