        力士樂電液伺服閥廣泛地應(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).
        Rexroth伺服閥結(jié)構(gòu)比較復(fù)雜，造價(jià)高，對(duì)油的質(zhì)量和清潔度要求高。新型的伺服閥正試圖克服這些缺點(diǎn)，例如利用電致伸縮元件的伺服閥，使結(jié)構(gòu)大為簡化。另一個(gè)方向是研制特殊的工作油（如電氣粘性油）。這種工作油能在電磁的作用下改變粘性系數(shù)。利用這一性質(zhì)就可通過電信號(hào)直接控制油流。
