EMG伺服閥 SV1-10/32/315/6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。伺服閥廣泛地應(yīng)用于電液位置，速度加速度，力伺服系統(tǒng)，以及伺服振動(dòng)發(fā)生器中，它具有體積小，結(jié)構(gòu)緊湊，功率放大系數(shù)高，控制精度高，直線性好，死區(qū)小，靈敏度高，動(dòng)態(tài)性能好以及響應(yīng)速度快等優(yōu)點(diǎn)

典型的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)，檔板向右移動(dòng)，使右邊噴嘴的節(jié)流作用加強(qiáng)，流量減少，右側(cè)背壓上升；同時(shí)使左邊噴嘴節(jié)流作用減小，流量增加，左側(cè)背壓下降。閥芯兩端的作用力失去平衡， 閥芯遂向左移動(dòng)。高壓油從S流向C2，送到負(fù)載

負(fù)載回油通過(guò) C1流過(guò)回油口，進(jìn)入油箱。閥芯的位移量與力矩馬達(dá)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(dá)的差動(dòng)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。

伺服閥主要用在電氣液壓伺服系統(tǒng)中作為執(zhí)行元件。

在伺服系統(tǒng)中，液壓執(zhí)行機(jī)構(gòu)同電氣及氣動(dòng)執(zhí)行機(jī)構(gòu)相比，具有快速性好、單位重量輸出功率大、傳動(dòng)平穩(wěn)、抗干擾能力強(qiáng)等特點(diǎn)。另一方面，在伺服系統(tǒng)中傳遞信號(hào)和校正特性時(shí)多用電氣元件。因此，現(xiàn)代的伺服系統(tǒng)也都采用電液方式，伺服閥就是這種系統(tǒng)的必需元件。
