力士樂二通電動插裝式高頻響閥2WRCE...-2X/S...包括以下組件：二級先導控制閥（1）—帶干式力矩馬達、低摩擦噴嘴擋板放大器和、閥芯位置的機械反饋；一個主級（2），用于流量控制；感應式位置傳感器（3），其鐵芯（4）安裝到三級閥芯（5）；集成閉環控制電子元件（6）。
Rexroth二通高頻響插裝閥的功能：集成電子元件通過提供與系統偏差成比例的電流，比較控制值和實際值并控制先導控制閥的力矩馬達。先導控制閥移動到比例控制位置并控制流進或流出控制室 A（7）和 B（8）的流量，通過閉環控制閥啟動主閥芯（5），直至系統偏差為 0。因此，主閥芯的行程通過控制值的比例進行控制。必須注意的是，流量還取決于閥的壓降。
