Rexroth力士乐4WRA 10 E1-30-2X/G24K4/V比例换向阀
在阀板设计中两位四通及三位四通比例方向阀用作直动式设备。通过带对中螺纹和可拆卸线圈的比例电磁铁进行操作。线圈由外部控制电子元件进行控制。
设置：
阀门的基本构成包括：
带连接面的壳体 (1) ‐
带有压缩弹簧（3 和 4）的控制阀芯 (2) ‐
带对中螺纹的线圈（5 和 6） ‐
功能：
线圈（5 和 6）断电后，通过压缩弹簧（3 和 4）使控制阀芯 (2) 保持在中心位置 ‐
通过为比例电磁铁通电直接对控制阀芯 (2) 进行操作，例如控制线圈“b”(6) ‐
将控制阀芯 (2) 与电气输入信号成比例地向左移动 ?
通过具有渐进流体特性的节流横截面，进行从 P 到 A 及从 B 到 T 的连接 ?
关闭线圈 (6) ‐
控制阀芯 (2) 在压缩弹簧 (3) 的作用下返回到中心位置
带两个阀芯位置的阀门（型号 4WRA...A...）：
基本上，此型号阀的功能与带三个阀芯位置的阀门功能相对应。但是，此双阀芯位置阀仅配有线圈“a”。它配有带 NG 6 的保护塞 (8.1) 或带 NG10 的盖 (8.2) 来代替第二个比例电磁铁。
注意：
不得让油箱管路排空运行。在相应的安装条件下，必须安装一个预载阀（预载压力约为 2 bar）。
