　另一种是连续控制：阀口可以根据需要打开任意一个开度，由此控制通过流量的大小，这类阀有手动控制的，如节流阀，也有电控的，如比例阀、伺服阀。 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 

　　所以使用比例阀或伺服阀的目的就是：以电控方式实现对流量的节流控制（当然经过结构上的改动也可实现压力控制等），既然是节流控制 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 ，就必然有能量损失，伺服阀和其它阀不同的是，它的能量损失更大一些，因为它需要一定的流量来维持前置级控制油路的工作。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 

　　伺服阀的主阀一般来说和换向阀一样是滑阀结构，只不过阀芯的换向不是靠电磁铁来推动，而是靠前置级阀输出的液压力来推动，这一点和电液换向阀比较相似，只不过电液换向阀的前置级阀是电磁换向阀，而伺服阀的前置级阀是动态特性比较好的喷嘴挡板阀或射流管阀。
