伺服閥其實(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最高的。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。

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。

1）公稱壓力：這個(gè)參數(shù)與其它通用閥門(mén)的含義是一樣的，是根據(jù)管道公稱壓力來(lái)定；
2）工作壓力：如果工作壓力低則必須選用直動(dòng)或分步直動(dòng)式原理；最低工作壓差在0.04Mpa以上時(shí)直動(dòng)式、分步直動(dòng)式、先導(dǎo)式均可選用。
4、電氣選擇：電壓規(guī)格應(yīng)盡量?jī)?yōu)先選用AC220V、DC24較為方便。
