G771K208A 是 MOOG 公司生產(chǎn)的一款伺服閥，具有內(nèi)部并聯(lián)接線和反極性保護(hù)功能。這款伺服閥由永磁力矩馬達(dá)、噴嘴、檔板、閥芯、閥套和控制腔組成。當(dāng)輸入線圈通入電流時(shí)，檔板移動(dòng)，導(dǎo)致噴嘴節(jié)流作用變化，從而控制閥芯兩端的壓力平衡，實(shí)現(xiàn)閥芯的移動(dòng)。閥芯的位移量與力矩馬達(dá)的輸入電流成正比，實(shí)現(xiàn)精確的流量控制。
該伺服閥的物理參數(shù)如下：
型號(hào)：G771K208A
安裝型式：尺寸 04（ISO 10372-04-04-0-92）
重量：1.0 至 1.7 kg（2.2 至 3.8 lbs）
附加選擇包括高零偏、磁性零位調(diào)節(jié)、透氣馬達(dá)蓋、特殊閥芯閥套（BSA）配合、內(nèi)部并聯(lián)接線、反極性保護(hù)和超高響應(yīng)。
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.
