力士樂比例閥是用來控制伺服油缸的。伺服油缸的縮進(jìn)和伸長同時(shí)用電液伺服閥來加油壓。力士樂比例閥用電磁力馬達(dá)來控制它的開關(guān)。力士樂比例閥有一個(gè)閥位反饋器，把閥門位置反饋到主控室的伺服控制器中。力士樂比例閥通過輸出正電流和負(fù)電流來控制電磁力馬達(dá)的開關(guān)。

另一種力士樂比例閥是連續(xù)控制：閥口可以根據(jù)需要打開任意一個(gè)開度，由此控制通過流量的大小，這類閥有手動(dòng)控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。

REXROTH力士樂比例閥一般來說和換向閥一樣是滑閥結(jié)構(gòu)，只不過閥芯的換向不是靠電磁鐵來推動(dòng)，而是靠前置級(jí)閥輸出的液壓力來推動(dòng)，這一點(diǎn)和電液換向閥比較相似，只不過電液換向閥的前置級(jí)閥是電磁換向閥，而伺服閥的前置級(jí)閥是動(dòng)態(tài)特性比較好的噴嘴擋板閥或射流管閥。

　　REXROTH力士樂比例閥也就是說，伺服閥的主閥是靠前置級(jí)閥的輸出壓力來控制的，而前置級(jí)閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置級(jí)閥就不能輸出足夠的壓力來推動(dòng)主閥芯動(dòng)作。
