　伺服閥的主閥一般來說和換向閥一樣是滑閥結(jié)構(gòu)

，只不過閥芯的換向不是靠電磁鐵來推動，而是靠前置級閥輸出的液壓力來推動，這一點和電液換向閥比較相似，只不過電液換向閥的前置級閥是電磁換向閥，而伺服閥的前置級閥是動態(tài)特性比較好的噴嘴擋板閥或射流管閥。?

　　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)負載為零的時候，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GHP1AQ-D-20?GHP1A2-D-2?GHP1A2-D-3?GHP1A2-D-4?GHP1A2-D-5?GHP1A2-D-6?GHP1A2-D-7?GHP1A2-D-9?GHP1A2-D-11?GHP1A2-D-13?GHP1A2-D-16?GHP1A2-D-20?GHP2-D-6?GHP2-D-9?GHP2-D-10?GHP2-D-12?GHP2-D-13?GHP2-D-16?GHP2-D-20?GHP2-D-22?GHP2-D-25?GHP2-D-30?GHP2-D-34?GHP2-D-37?GHP2-D-40?GHP2-D-50?GHP2A-D-6?GHP2A-D-9?GHP2A-D-10?GHP2A-D-12?GHP2A-D-13?GHP2A-D-16?GHP2A-D-20?GHP2A-D-22?GHP2A-D-25?GHP2A-D-30?GHP2A-D-34?GHP2A-D-37?GHP2A-D-40?GHP2A-D-50?GHP2A3-D-6?GHP2A3-D-9?GHP2A3-D-10?GHP2A3-D-12?GHP2A3-D-13?GHP2A3-D-16?GHP2A3-D-20?GHP2A3-D-22?GHP2A3-D-25?GHP2A3-D-30?GHP2A3-D-34?GHP2A3-D-37?GHP2A3-D-40?GHP2A3-D-50?GHP2BK1-D-6?GHP2BK1-D-9?GHP2BK1-D-10?GHP2BK1-D-12?GHP2BK1-D-13?GHP2BK1-D-16?GHP2BK1-D-20?GHP2BK1-D-22?GHP2BK1-D-25?GHP2BK1-D-30?GHP2BK1-D-34?GHP2BK1-D-37?GHP2BK1-D-40?GHP2BK2-D-6?GHP2BK2-D-9?GHP2BK2-D-10?GHP2BK2-D-12?GHP2BK2-D-13?GHP2BK2-D-16?GHP2BK2-D-20?GHP2BK2-D-22?GHP2BK2-D-25?GHP2BK2-D-30?GHP2BK2-D-34?GHP2BK2-D-37?GHP2BK2-D-40?GHP2BK4-D-6?GHP2BK4-D-9?GHP2BK4-D-10?GHP2BK4-D-12?GHP2BK4-D-13?GHP2BK4-D-16?GHP2BK4-D-20?GHP2BK4-D-22?GHP2BK4-D-25?GHP2BK4-D-30?GHP2BK4-D-34?GHP2BK4-D-37?GHP2BK4-D-40?GHP2BK7-D-6?GHP2BK7-D-9?GHP2BK7-D-10?GHP2BK7-D-12?GHP2BK7-D-13?GHP2BK7-D-16?GHP2BK7-D-20?GHP2BK7-D-22?GHP2BK7-D-25?GHP2BK7-D-30?GHP2BK7-D-34?GHP2BK7-D-37?GHP2BK7-D-40?GHP3-D-30?GHP3-D-33?GHP3-D-40?GHP3-D-50?GHP3-D-60?GHP3-D-66?GHP3-D-80?GHP3-D-94?GHP3-D-110?GHP3-D-120?GHP3-D-135?GHP3A-D-30?GHP3A-D-33?GHP3A-D-40?GHP3A-D-50?GHP3A-D-60?GHP3A-D-66?GHP3A-D-80?GHP3A-D-94?GHP3A-D-110?GHP3A-D-120?GHP3A-D-135?GHP3A2-D-30?，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。
