REXROTH方向伺服阀外部控制电子元件
力士乐方向伺服阀用于外部控制电子元件，为控制该阀，使用外部控制电子元件控制装置（伺服放大器），该控制装置将模拟输入信号（控制值）放大到输出信号需要的电平，来为该伺服阀提供电流调节控制。
REXROTH方向伺服阀外部控制电子元件
REXROTH方向伺服阀为了放大模拟输入信号，在该阀中集成了专门与此阀类型匹配的控制电气元件。该电气元件已安装到了力矩马达帽中的插入式连接器。
力士乐4WS(E)2EM6-2X/…方向伺服阀是带符合ISO4401-03-02-0-05的油口安装面的电动操作式2级方向伺服阀。它们主要用于位置，方向，压力或速率的闭环控制。Rexroth方向伺服阀由机电转换器（力矩马达），液压放大器（喷嘴挡板原理）和衬套（第2级）（阀芯通过机械反馈连接到力矩马达）中的控制阀芯组成。
作为施加在力矩马达的线圈上的电气输入信号的结果，*磁体产生的力作用于电枢，该力与弹性管联用产生扭矩。这导致通过销连接到弹性管的挡板从两个控制喷嘴之间的中心位置移动开，并且通过控制阀芯的两侧表面产生压差。该压差导致阀芯位置的改变，并建立压力油口与执行机构油口之间的连通油路，同时，也建立另一个执行机构油口与回流油口的连通油路。
