Z2S 型單向閥是采用疊加閥板設計的先導式單向閥。
用于一個或兩個執行機構油口的無泄漏阻塞，甚至能夠用于長期停機的情況。
在方向 A① 到 A② 或 B① 到 B② 上，可以自由流動；在相反方向上，流動被阻塞。
例如，如果閥門的流向是從 A① 到 A②，控制閥芯 (1) 將向 B 側方向移動，打開球座閥 (2) 并推動閥心 (3) 偏離其閥座。液壓油現在即可從 B② 流向 B?。
為了可以安全地封閉球座閥 (2)，必須液壓卸載控制閥芯 (1)（請參閱油路示例）。
由于預開口的存在，加壓液體可以進行衰減降壓。這樣避免了可能的換向沖擊。
預開口
由于使用的是具有擴大的開口控制面積比的兩層結構，使用較低的先導壓力也可以安全卸載。 ?
避免由于執行機構側的壓力容積的衰減降壓而導致的換向沖擊。
