MOOG伺服閥由永磁力矩馬達、噴嘴、檔板、閥芯、閥套和控制腔組成。當輸入線圈通入電流 伺服閥時，檔板向右移動，使右邊噴嘴的節(jié)流作用加強，流量減少，右側背壓上升;同時使左邊噴嘴節(jié)流作用減小，流量增加，左側背壓下降。閥芯兩端的作用力失去平衡, 閥芯遂向左移動。高壓油從S流向C2，送到負載。負載回油通過 C1流過回油口，進入油箱。閥芯的位移量與力矩馬達的輸入電流成正比，作用在閥芯上的液壓力與彈簧力相平衡，因此在平衡狀態(tài)下力矩馬達的差動電流與閥芯的位移成正比。如果輸入的電流反向，則流量也反向。

MOOG穆格伺服閥主要用在電氣液壓伺服系統(tǒng)中作為執(zhí)行元件（見液壓伺服系統(tǒng)）。在伺服系統(tǒng)中，液壓執(zhí)行機構同電氣及氣動執(zhí)行機構相比，具有快速性好、單位重量輸出功率大、傳動平穩(wěn)、抗干擾能力強等特點。另一方面，在伺服系統(tǒng)中傳遞信號和校正特性時多用電氣元件。因此，現(xiàn)代高性能的伺服系統(tǒng)也都采用電液方式，伺服閥就是這種系統(tǒng)的必需元件。

MOOG穆格伺服閥主要是指電液伺服閥,它在接受電氣模擬信號后，相應輸出調(diào)制的流量和壓力。它既是電液轉換元件，也是功率放大元件，它能夠將小功率的微弱電氣輸入信號轉換為大功率的液壓能（流量和壓力）輸出。
