MOOG伺服閥放大器，美國(guó)MOOG，穆格伺服閥結(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)就可通過電信號(hào)直接控制油流。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,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。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。
