另一種是連續(xù)控制：閥口可以根據(jù)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 

所以使用比例閥或伺服閥的目的就是：以電控方式實現(xiàn)對流量的節(jié)流控制（當(dāng)然經(jīng)過結(jié)構(gòu)上的改動也可實現(xiàn)壓力控制等），既然是節(jié)流控制 GHM1AQ-R-6-E1 GHM1AQ-R-7-E1 GHM1AQ-R-9-E1 GHM1AQ-R-11-E1 GHM1AQ-R-13-E1 GHM1AQ-R-16-E1 GHM2-R-6-E1 GHM2-R-9-E1 GHM2-R-10-E1 GHM2-R-12-E1 GHM2-R-13-E1 GHM2-R-16-E1 GHM2-R-20-E1 GHM2-R-22-E1 GHM2-R-25-E1 GHM2-R-30-E1 GHM2-R-34-E1 GHM2-R-37-E1 GHM2-R-40-E1 GHM2A-R-6-E1 GHM2A-R-9-E1 GHM2A-R-10-E1 GHM2A-R-12-E1 GHM2A-R-13-E1 GHM2A-R-16-E1 GHM2A-R-20-E1 GHM2A-R-22-E1 GHM2A-R-25-E1 GHM2A-R-30-E1 GHM2A-R-34-E1 GHM2A-R-37-E1 GHM2A-R-40-E1 GHM2A3-R-6-E1 GHM2A3-R-9-E1 GHM2A3-R-10-E1 GHM2A3-R-12-E1 GHM2A3-R-13-E1 GHM2A3-R-16-E1 GHM2A3-R-20-E1 GHM2A3-R-22-E1 GHM2A3-R-25-E1 GHM2A3-R-30-E1 GHM2A3-R-34-E1 GHM2A3-R-37-E1 GHM2A3-R-40-E1 GHM2BK1-R-6-E1 GHM2BK1-R-9-E1 GHM2BK1-R-10-E1 GHM2BK1-R-12-E1 GHM2BK1-R-13-E1 GHM2BK1-R-16-E1 GHM2BK1-R-20-E1 GHM2BK1-R-22-E1 GHM2BK1-R-25-E1 GHM2BK1-R-30-E1 GHM2BK1-R-34-E1 GHM2BK1-R-37-E1 GHM2BK1-R-40-E1 GHM2BK2-R-6-E1 ，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因為它需要一定的流量來維持前置級控制油路的工作。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 GHM3A2-R-120-E1 GHM3A2-R-135-E1 GHM3BK1-R-33-E1 GHM3BK1-R-40-E1 GHM3BK1-R-50-E1 GHM3BK1-R-60-E1 GHM3BK1-R-66-E1 GHM3BK1-R-80-E1 GHM35-R-66-E1 GHM35-R-80-E1 GHM35-R-94-E1 GHM35-R-110-E1    GHM35-R-120-E1 GHM35-R-135-E1 0.25D18 0.25D24 0.25D30 0.25D36 0.25D48 0.25D60 0.25D0.50 0.25D0.75 0.25D1.00 0.25D1.30 0.25D1.60 0.25D2.00 K0.25D18 K0.25D24 K0.25D30 K0.25D36 K0.25D48 K0.25D60 K0.25D0.50 K0.25D0.75 K0.25D1.00 K0.25D1.30 K0.25D1.60 K0.25D2.00 0.25D18KA 0.25D24KA 0.25D30KA 0.25D36KA 0.25D48KA 0.25D60KA 0.25D0.50KA 0.25D0.75KA 0.25D1.00KA 0.25D1.30KA 0.25D1.60KA 0.25D2.00KA U0.25D18 U0.25D24 U0.25D30 U0.25D36 U0.25D48 U0.25D60 U0.25D0.50 U0.25D0.75 U0.25D1.00 U0.25D1.30 U0.25D1.60 U0.25D2.00 UK0.25D18 UK0.25D24 UK0.25D30 UK0.25D36 UK0.25D48 UK0.25D60 UK0.25D0.50 UK0.25D0.75 UK0.25D1.00 UK0.25D1.30 UK0.25D1.60 UK0.25D2.00 UK0.25D18KA UK0.25D24KA UK0.25D30KA UK0.25D36KA UK0.25D48KA UK0.25D60KA UK0.25D0.50KA UK0.25D0.75KA UK0.25D1.00KA UK0.25D1.30KA UK0.25D1.60KA UK0.25D2.00KA  0.25D18GRO 0.25D24GRO 0.25D30GRO 0.25D36GRO 0.25D48GRO 0.25D60GRO 0.25D0.50GRO 0.25D0.75GRO 0.25D1.00GRO 0.25D1.30GRO 0.25D1.60GRO U0.25D18GRO U0.25D24GRO U0.25D30GRO U0.25D36GRO U0.25D48GRO U0.25D60GRO U0.25D0.50GRO 

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。
