MOOG伺服阀由永磁力矩马达、喷嘴、档板、阀芯、阀套和控制腔组成。当输入线圈通入电流 伺服阀时，档板向右移动，使右边喷嘴的节流作用加强，流量减少，右侧背压上升;同时使左边喷嘴节流作用减小，流量增加，左侧背压下降。阀芯两端的作用力失去平衡, 阀芯遂向左移动。高压油从S流向C2，送到负载。负载回油通过 C1流过回油口，进入油箱。阀芯的位移量与力矩马达的输入电流成正比，作用在阀芯上的液压力与弹簧力相平衡，因此在平衡状态下力矩马达的差动电流与阀芯的位移成正比。如果输入的电流反向，则流量也反向。

MOOG穆格伺服阀主要用在电气液压伺服系统中作为执行元件（见液压伺服系统）。在伺服系统中，液压执行机构同电气及气动执行机构相比，具有快速性好、单位重量输出功率大、传动平稳、抗干扰能力强等特点。另一方面，在伺服系统中传递信号和校正特性时多用电气元件。因此，现代高性能的伺服系统也都采用电液方式，伺服阀就是这种系统的必需元件。

MOOG穆格伺服阀主要是指电液伺服阀,它在接受电气模拟信号后，相应输出调制的流量和压力。它既是电液转换元件，也是功率放大元件，它能够将小功率的微弱电气输入信号转换为大功率的液压能（流量和压力）输出。
