也就是說，伺服閥的主閥是靠前置級閥的輸出壓力來控制的，而前置級閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置級閥就不能輸出足夠的壓力來推動主閥芯動作。

而我們知道，當(dāng)負(fù)載為零的時(shí)候，如果四通滑閥完全打開，p口壓力＝t口壓力＋閥口壓力損失（忽略油路上的其它壓力損失），如果閥口壓力損失很小，t口壓力又為零，那么p口的壓力就不足以供給前置級閥來推動主閥芯，整個(gè)伺服閥就失效了。所以伺服閥的閥口做得偏小，即使在閥口全開的情況下，也要有一定的壓力損失，來維持前置級閥的正常工作。parker止回閥D41FHB31C1NE0048

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)，在很多對動態(tài)特性要求高的場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。動態(tài)要求低一點(diǎn)的，基本上都是比例閥的PAVC1002L422
