REXROTH方向伺服閥外部控制電子元件
力士樂方向伺服閥用于外部控制電子元件，為控制該閥，使用外部控制電子元件控制裝置（伺服放大器），該控制裝置將模擬輸入信號(hào)（控制值）放大到輸出信號(hào)需要的電平，來為該伺服閥提供電流調(diào)節(jié)控制。
REXROTH方向伺服閥外部控制電子元件
REXROTH方向伺服閥為了放大模擬輸入信號(hào)，在該閥中集成了專門與此閥類型匹配的控制電氣元件。該電氣元件已安裝到了力矩馬達(dá)帽中的插入式連接器。
力士樂4WS(E)2EM6-2X/…方向伺服閥是帶符合ISO4401-03-02-0-05的油口安裝面的電動(dòng)操作式2級(jí)方向伺服閥。它們主要用于位置，方向，壓力或速率的閉環(huán)控制。Rexroth方向伺服閥由機(jī)電轉(zhuǎn)換器（力矩馬達(dá)），液壓放大器（噴嘴擋板原理）和襯套（第2級(jí)）（閥芯通過機(jī)械反饋連接到力矩馬達(dá)）中的控制閥芯組成。
作為施加在力矩馬達(dá)的線圈上的電氣輸入信號(hào)的結(jié)果，*磁體產(chǎn)生的力作用于電樞，該力與彈性管聯(lián)用產(chǎn)生扭矩。這導(dǎo)致通過銷連接到彈性管的擋板從兩個(gè)控制噴嘴之間的中心位置移動(dòng)開，并且通過控制閥芯的兩側(cè)表面產(chǎn)生壓差。該壓差導(dǎo)致閥芯位置的改變，并建立壓力油口與執(zhí)行機(jī)構(gòu)油口之間的連通油路，同時(shí)，也建立另一個(gè)執(zhí)行機(jī)構(gòu)油口與回流油口的連通油路。
