此型號的閥門是電動操作式二級伺服方向閥，其油口安裝面符合 ISO 4401-03-02-0-05 標準。 它們主要用于控制位置、力、壓力或速率。
這些閥門由機電轉換器（力矩馬達）、液壓放大器（原理：噴嘴擋板）和套筒（第二級）中的控制閥芯（通過機械反饋連接到力矩馬達）組成。
力矩馬達線圈上的電氣輸入信號通過磁體產生作用于電樞的力，并與彈性管一起產生扭矩。這導致通過螺栓連接到彈性管的擋板從兩個控制噴嘴之間的中心位置移開，并且在控制閥芯的前側產生壓差。壓差導致閥芯改變位置，并導致壓力油口連接一個執行機構油口，同時，另一個執行機構油口連接到回流油口。
控制閥芯通過彎曲彈簧（機械反饋）連接到擋板或力矩馬達。閥芯的位置將改變，直到彎曲彈簧的反饋扭矩和力矩馬達的電磁扭矩達到平衡并且噴嘴擋板系統的壓差變為零。
因此，控制閥芯的行程和伺服閥的流量是與電氣輸入信號成比例來控制的。必須注意的是，流量取決于閥壓降。
用于外部控制電子元件的型號 4WS2EM 6-2X/…
外部控制電子元件（伺服放大器）操作閥門并放大模擬輸入信號（控制值），以便通過輸出信號以流量控制形式驅動伺服閥。
帶有 OBE 的型號 4WSE2EM 6-2X/…
要放大模擬輸入信號，需集成特別針對此閥類型進行過調整的控制電子元件。它們與位于力矩馬達蓋帽中的連接器相連接。
