G771K208A 是 MOOG 公司生产的一款伺服阀，具有内部并联接线和反极性保护功能。这款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时，档板移动，导致喷嘴节流作用变化，从而控制阀芯两端的压力平衡，实现阀芯的移动。阀芯的位移量与力矩马达的输入电流成正比，实现精确的流量控制。
该伺服阀的物理参数如下：
型号：G771K208A
安装型式：尺寸 04（ISO 10372-04-04-0-92）
重量：1.0 至 1.7 kg（2.2 至 3.8 lbs）
附加选择包括高零偏、磁性零位调节、透气马达盖、特殊阀芯阀套（BSA）配合、内部并联接线、反极性保护和超高响应。
The G771K208A is a servo valve manufactured by MOOG with internal parallel connection and reverse polarity protection. This servo valve is composed of permanent magnet torque motor, nozzle, stop plate, valve core, valve sleeve and control chamber. When the input coil passes the current, the baffle moves, causing the nozzle throttling action to change, thereby controlling the pressure balance at both ends of the spool to achieve the movement of the spool. The displacement of the spool is proportional to the input current of the torque motor to achieve accurate flow control.
The physical parameters of the servo valve are as follows:
Model: G771K208A
Installation type: Dimension 04 (ISO 10372-04-04-0-92)
Weight: 1.0 to 1.7 kg (2.2 to 3.8 lbs)
Additional options include high zero bias, magnetic zero adjustment, breathable motor cover, special spool valve sleeve (BSA) fit, internal parallel wiring, reverse polarity protection and ultra-high response.
