廣泛應(yīng)用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機(jī)械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域

力士樂(lè)比例閥的閥芯的運(yùn)動(dòng)是采用比例電磁鐵控制，使輸出的壓力或流量與輸入的電流成正比。所以可用改變輸入電信號(hào)的方法對(duì)壓力、流量進(jìn)行連續(xù)控制。有的閥還兼有控制流量大小和方向的功能。根據(jù)功能力士樂(lè)比例閥也可分為壓力閥、流量閥和換向閥三大類。 
力士樂(lè)比例閥

德國(guó)力士樂(lè)比例閥的閥芯的運(yùn)動(dòng)是采用比例電磁鐵控制，使輸出的壓力或流量與輸入的電流成正比。所以可用改變輸入電信號(hào)的方法對(duì)壓力、流量進(jìn)行連續(xù)控制。有的閥還兼有控制流量大小和方向的功能。力士樂(lè)比例閥根據(jù)功能可分為比例流量閥、比例壓力閥、比例換向閥三大類。以結(jié)構(gòu)形式劃分電液比例閥主要有兩類：一類是螺旋插裝式比例閥(screwin cartridge proportional valve)，另一類是滑閥式比例閥(spool proportional valve)。

德國(guó)力士樂(lè)REXROTH比例閥的螺紋將電磁比例插裝件固定油路集成塊上元件，螺旋插裝閥具有應(yīng)用靈活、節(jié)省管路和成本低廉等特點(diǎn)，近年來(lái)工程機(jī)械上應(yīng)用越來(lái)越廣泛。常用螺旋插裝式比例閥有二通、三通、四通和多通等形式，二通式比例閥主比例節(jié)流閥，它常它元件一起構(gòu)成復(fù)合閥，對(duì)流量、壓力進(jìn)行控制；三通式比例閥主比例減壓閥，也是移動(dòng)式機(jī)械液壓系統(tǒng)中應(yīng)用較多比例閥，它主對(duì)液動(dòng)操作多路閥先導(dǎo)油路進(jìn)行操作。利用三通式比例減壓閥可以代替?zhèn)鹘y(tǒng)手動(dòng)減壓式先導(dǎo)閥，它比手動(dòng)先導(dǎo)閥具有更多靈活性和更高控制精度。可以制成如圖1所示比例伺服控制手動(dòng)多路閥，不同輸入信號(hào)，減壓閥使輸出活塞具有不同壓力或流量進(jìn)而實(shí)現(xiàn)對(duì)多路閥閥芯位移進(jìn)行比例控制。四通或多通螺旋插裝式比例閥可以對(duì)工作裝置實(shí)現(xiàn)單獨(dú)控制。
德國(guó)力士樂(lè)REXROTH比例閥一種是開(kāi)關(guān)控制：要么全開(kāi)、要么全關(guān)，流量要么zui大、要么zui小，沒(méi)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。
德國(guó)力士樂(lè)REXROTH比例閥另一種是連續(xù)控制：閥口可以根據(jù)需要打開(kāi)任意一個(gè)開(kāi)度，由此控制通過(guò)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(lè)比例閥比例閥或伺服閥的目的就是：以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制(當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)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?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。
德國(guó)力士樂(lè)REXROTH比例閥一般來(lái)說(shuō)和換向閥一樣是滑閥結(jié)構(gòu)，只不過(guò)閥芯的換向不是靠電磁鐵來(lái)推動(dòng)，而是靠前置級(jí)閥輸出的液壓力來(lái)推動(dòng)，這一點(diǎn)和電液換向閥比較相似，只不過(guò)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。
德國(guó)力士樂(lè)REXROTH比例閥也就是說(shuō)，伺服閥的主閥是靠前置級(jí)閥的輸出壓力來(lái)控制的，而前置級(jí)閥的壓力則來(lái)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(lái)推動(dòng)主閥芯動(dòng)作。
德國(guó)力士樂(lè)REXROTH比例閥其實(shí)缺點(diǎn)極多：能耗浪費(fèi)大、容易出故障、抗污染能力差、價(jià)格昂貴等等等等，好處只有一個(gè)：動(dòng)態(tài)性能是所有液壓閥中zui高的。就憑著這一個(gè)優(yōu)點(diǎn)，在很多對(duì)動(dòng)態(tài)特性要求高的場(chǎng)合不得不使用伺服閥，如飛機(jī)火箭的舵機(jī)控制、汽輪機(jī)調(diào)速等等。動(dòng)態(tài)要求低一點(diǎn)的，基本上都是比例閥的天下了。一般說(shuō)來(lái)，好像伺服系統(tǒng)都是閉環(huán)控制，比例多用于開(kāi)環(huán)控制；其次比例閥類型要多，有比例壓力、流量控制閥等，控制比伺服藥?kù)`活一些。從他們內(nèi)部結(jié)構(gòu)看，伺服閥多是零遮蓋，比例閥則有一定的死區(qū)，控制精度要低，向應(yīng)要慢。但從發(fā)展趨勢(shì)看，特別在比例方向流量控制閥和伺服閥方面，兩者性能差別逐漸在縮小，另外比例閥的成本比伺服閥要低許多，抗污染能力也強(qiáng)！

REXROTH R900943858 4WRZ25W8-825-7X/6EG24N9EK4/V  液控伺服閥主要是指電液伺服閥,它在接受電氣模擬信號(hào)后，相應(yīng)輸出調(diào)制的流量和壓力。它既是電液轉(zhuǎn)換元件，也是功率放大元件，它能夠?qū)⑿」β实奈⑷蹼姎廨斎胄盘?hào)轉(zhuǎn)換為大功率的液壓能（流量和壓力）輸出。在電液伺服系統(tǒng)中，它將電氣部分與液壓部分連接起來(lái)，實(shí)現(xiàn)電液信號(hào)的轉(zhuǎn)換與液壓放大。電液伺服閥是電液伺服系統(tǒng)控制的核心。
液控伺服閥是在伺服系統(tǒng)中將電信號(hào)輸入轉(zhuǎn)換為功率較大的壓力或流量壓力信號(hào)輸出的執(zhí)行元件。它是一種電液轉(zhuǎn)換和功率放大元件。伺服閥的靈敏度高，快速性好，能將很小的電信號(hào)（例如10毫安）轉(zhuǎn)換成很大的液壓功率（如幾十匹馬力以上），可以驅(qū)動(dòng)多種類型的負(fù)載。過(guò)去人們?cè)褔娮鞕n板閥、射流管或滑閥伺服馬達(dá)等液壓放大裝置都列入伺服閥范圍內(nèi)。20世紀(jì)70年代以來(lái)，伺服閥一般僅指電液伺服閥。
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(見(jiàn)圖)。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。表中是伺服閥的分類。
伺服閥主要用在電氣液壓伺服系統(tǒng)中作為執(zhí)行元件（見(jiàn)液壓伺服系統(tǒng)）。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*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)代高性能的伺服系統(tǒng)也都采用電液方式，伺服閥就是這種系統(tǒng)的必需元件。
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(jiǎn)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(guò)電信號(hào)直接控制油流。
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).
