　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。?
