2S型液控單向閥：
1、用于垂直疊加安裝；
2、按需要可以無泄漏封閉一個或兩個工作油口。
說明：
1、Z2S型閥是疊加式結構的液控單向閥。
2、即使長時間的保壓，一個或兩個的工作油口仍保持無泄漏的密封。
3、由A至A1或由B至B1是自由流通的，而反方向則封閉。
4、如油從B流經閥至B1，壓力作用在活塞上。活塞便向左運動，將錐閥芯推離其閥座。此時油便可從A1流向A。
5、為保證錐閥芯正確閉合，當控制閥處于時，閥的工作油口與油箱想通。

        注意事項
1、液壓系統用的介質必須過濾；過濾精度至少20μm。
2、液壓系統用的油箱必須密封；并加空氣過濾器。
3、華德產品出廠時不帶底板。（如需用請訂貨）。
4、固定螺栓請按樣本中列的參數選用。
5、與閥連接的表面粗糙度要求0.8R。
6、與閥連接的平面度要求0.01/100mm。
