另一種是連續(xù)控制：閥口可以根據需要打開任意一個開度，由此控制通過流量的大小，這類閥有手動控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。 GHM2BK2-R-22-E1 GHM2BK2-R-25-E1 GHM2BK2-R-30-E1 GHM2BK2-R-34-E1 GHM2BK2-R-37-E1 GHM2BK2-R-40-E1 GHM2BK4-R-6-E1 GHM2BK4-R-9-E1 GHM2BK4-R-10-E1 GHM2BK4-R-12-E1 GHM2BK4-R-13-E1 GHM2BK4-R-16-E1 GHM2BK4-R-20-E1 GHM2BK4-R-22-E1 GHM2BK4-R-25-E1 GHM2BK4-R-30-E1 GHM2BK4-R-34-E1 GHM2BK4-R-37-E1 GHM2BK4-R-40-E1 GHM2BK7-R-6-E1 GHM2BK7-R-9-E1 GHM2BK7-R-10-E1 GHM2BK7-R-12-E1 GHM2BK7-R-13-E1 GHM2BK7-R-16-E1 GHM2BK7-R-20-E1 GHM2BK7-R-22-E1 GHM2BK7-R-25-E1 GHM2BK7-R-30-E1 GHM2BK7-R-34-E1 GHM2BK7-R-37-E1 GHM2BK7-R-40-E1 GHM3-R-33-E1 GHM3-R-40-E1 GHM3-R-50-E1 GHM3-R-60-E1 GHM3-R-66-E1 GHM3-R-80-E1 GHM3-R-94-E1 GHM3-R-110-E1 GHM3-R-120-E1 GHM3-R-135-E1 GHM3A-R-33-E1 GHM3A-R-40-E1 GHM3A-R-50-E1 GHM3A-R-60-E1 GHM3A-R-66-E1 GHM3A-R-80-E1 GHM3A-R-94-E1 GHM3A-R-110-E1 GHM3A-R-120-E1 GHM3A-R-135-E1 GHM3A2-R-33-E1 GHM3A2-R-40-E1 GHM3A2-R-50-E1 GHM3A2-R-60-E1 GHM3A2-R-66-E1 GHM3A2-R-80-E1 GHM3A2-R-94-E1 GHM3A2-R-110-E1

伺服閥的主閥一般來說和換向閥一樣是滑閥結構，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。
