比例伺服阀由永磁力矩马达、喷嘴、档板、阀芯、阀套和控制腔组成(见图)。当输入线圈 通入电流时，档板向右移动，使右边喷嘴的节流作用加强，流量减少，右侧背压上升；同 时使左边喷嘴节流作用减小，流量增加，左侧背压下降。阀芯两端的作用力失去平衡, 阀 芯遂向左移动。高压油从S流向C2，送到负载。负载回油通过 C1流过回油口，进入油箱。 阀芯的位移量与力矩马达的输入电流成正比，作用在阀芯上的液压力与弹簧力相平衡，因 此在平衡状态下力矩马达的差动电流与阀芯的位移成正比。如果输入的电流反向，则流量 也反向。

 

比例电磁铁的性能指标主要包括适用电压（电流）、推（拉）力和行程等。
根据电压可以分为12V直流，24V直流，110V交流，220V交流等。NG6阀用电磁铁推拉力一般为20-
70N，行程在 3-7mm之间。当怀疑某电磁阀卡滞或线圈烧毁时，可以将电磁阀反过来，看其行程是否在上述范围之内。
电磁铁的外特性主要表现为电阻。较常见的24V NG6电磁阀线圈阻值一般在16-26Ω之间，24V插装
阀线圈阻值一般在20-38Ω之间，24V比例阀线圈阻值一般在21-26Ω。理论上，电磁吸力与电流的平方成正比，所以12V线圈阻值一般为对应24V线圈的1/4左右。

电液换向阀由电磁换向阀和液动换向阀组成，其中电磁换向阀起先导作用，即用来改变液动换向阀控制压力油的方向;液动换向阀作为主阀，其工作位置由电磁换向阀的工作位置相应确定。电液换向阀根据控制油和回油方式分为:内控内泄式、内控外泄式、外控内泄式、外控外泄式四种。对于外控式阀，由于控制油是从电液换向阀之外的油路单独引入的，在使用时，无论内泄还是外泄，均不存在什么问题。对以内控方式供油的电液动换向阀，由于先导阀的供液口与主阀的P口是沟通的，若在中间位置是使泵卸荷的状态，如M、H、K等中位机能，在中位时主油路不能为控制油路提供主阀芯换向所必须的控制压力
