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、提升座阀、压缩弹簧、控制阀芯以及可选预开口球座阀组成。

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沿座阀方向移动，并推动提升座阀离开其阀座。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，控制阀芯两侧上的压力比与提升座阀或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）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，控制阀芯将向右移动。这样一来，滚珠和提升座阀将先后被推出阀座。

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。?

替换插头和可实现从 SV 型号到 SL 型号的修改。必须始终安装其中一个插头！
