Rexroth力士乐SV 6 PA2-6X/单向阀
SV 型单向阀是用于底板安装的先导式单向阀。用于一个执行机构油口的无泄漏阻塞，甚至能够用于长期停机的情况。
该阀主要由壳体 (1)、提升座阀 (2)、压缩弹簧 (3)、控制阀芯 (4) 以及可选预开口球座阀 (7) 组成。
座阀允许流体从方向 A 流向 B，而无需外部先导压力。
条件： pA > pB + 开启压力（压缩弹簧）。在相反方向上，座阀以液压方式紧闭。
油口 X 处的高先导压力足以使控制阀芯 (4) 沿座阀方向移动，并推动提升座阀 (2) 离开其阀座。这便实现了两个方向上的自由流动（主动保持打开）。
为确保座阀主动打开，控制阀芯 (4) 两侧上的压力比与提升座阀 (2) 或 (7) 上的面积比同样重要。
因此，提供了以下不同类型
SV（连接至 pA 的大阀芯端面 A2 (6)）或 ?
以及带预开口“A”和不带预开口“B”的型号。
型号“A”（带预开口）
该阀配有一个附加的预开口。通过对油口 X 加压，控制阀芯 (4) 将向右移动。这样一来，滚珠 (7) 和提升座阀 (2) 将先后被推出阀座。
注意！
型号“A”：
由于使用的是具有扩大的开口控制面积比的两层结构，使用较低的先导压力也可以安全卸载。 ?
避免由于执行机构侧的压力容积的衰减降压而导致的换向冲击。 ?
型号“B”：
阀门不带预开口时，可能会突然卸载所含的压力容积。产生的换向冲击不但会导致安装组件的过早磨损，还会形成噪音。 ?
替换插头 (9) 和 (10) 可实现从 SV 型号到 SL 型号的修改。必须始终安装其中一个插头！
