先导控制阀是直动式比例阀。控制边的尺寸经过优化,可用作比例方向阀型号 4WRKE 的先导控制阀。
比例电磁铁为带可拆卸线圈的耐压密闭型湿式插脚交流线圈。它们可将电流按比例转换为机械力。电流强度的增加会导致磁力相应增加。设定的磁力会在整个控制行程中保持不变。

先导控制阀主要由壳体(1),比例电磁铁(2 和 3),控制阀芯(4)和弹簧(5 和 6)组成。
在非工作情况下,两个执行机构都连接到油箱。如果两个线圈中的一个(2 或 3)励磁,则磁力会将阀的控制阀芯(4)向弹簧(5 或 6)移动。一旦超过遮盖区域,便会阻断两个执行机构中的一处连接,转而连接压力腔。流体从 P 流向主级的控制腔。

型号为 4WRKE 的阀是二级比例方向阀。它们用于控制液压油的流向和流量。主级是受位置控制的,这样,控制阀芯位置在流量较大的情况下也不会受液动力的影响。这种阀主要由先导控制阀(1),壳体(8),主控制阀芯(7),盖(5 和 6),对中弹簧(4),感应式位置传感器(9)和减压阀(3)组成。
如果没有输入信号,则主控制阀芯(7)就会被对中弹簧(4)固定在中心位置。盖(5 和 6)中的两个控制腔通过控制阀芯(2)连接到油箱。
主控制阀芯(7)通过感应式位置传感器(9)连接到合适的控制电子元件。主控制阀芯(7)的位置改变和放大器求和点控制值的改变,都能产生差动电压。比较控制值和实际值期间,通过电子元件确定可能的控制偏差,
