DANFOSS丹佛斯：液壓閥，液壓泵，液壓馬達(dá)。
REXROTH力士樂：液壓閥，柱塞泵，比例閥，電機(jī)及氣動(dòng)產(chǎn)品，滑塊。
VICKERS威格士：液壓閥，液壓泵，比例閥，放大器，伊頓柱塞馬達(dá)。
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***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。
一般說來(lái)，好像伺服系統(tǒng)都是閉環(huán)控制，比例多用于開環(huán)控制；其次比例閥類型要多，有比例壓力、流量控制閥等，控制比伺服要靈活一些。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，響應(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)！

流量閥
流量閥適用于需要進(jìn)行流量控制的水系統(tǒng)中，尤其適合于供熱，空調(diào)等非腐蝕性液體介質(zhì)的流量控制；安裝在水系統(tǒng)中，經(jīng)運(yùn)行前的一次調(diào)節(jié)，即可使系統(tǒng)流量自動(dòng)恒定在要求的設(shè)定值。
