德國力士樂伺服閥

德國REXROTH力士樂系列液壓元件：單向閥、方向閥、溢流閥、減壓閥、流量控制閥、二通插裝閥、比例閥、伺服閥、齒輪泵、葉片泵、柱塞泵、液壓馬達和泵閥部件閥對流量的控制可以分為兩種：
一種是開關控制：要么全開、要么全關，流量要么zui大、要么zui小，沒有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。
另一種是連續(xù)控制：閥口可以根據(jù)需要打開任意一個開度，由此控制通過流量的大小，這類閥有手動控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。
所以使用比例閥或伺服閥的目的就是：以電控方式實現(xiàn)對流量的節(jié)流控制（當然經(jīng)過結(jié)構(gòu)上的改動也可實現(xiàn)壓力控制等），既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因為它需要一定的流量來維持前置級控制油路的工作。
