德国力士乐REXROTH比例阀另一种是连续控制：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。
REXROTH力士乐比例阀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，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。
德国力士乐REXROTH比例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。
德国力士乐REXROTH比例阀也就是说，伺服阀的主阀是靠前置级阀的输出压力来控制的，而前置级阀的压力则来自于伺服阀的入口p，假如p口的压力不足，前置级阀就不能输出足够的压力来推动主阀芯动作。
德国力士乐REXROTH比例阀其实缺点极多：能耗浪费大、容易出故障、抗污染能力差、价格昂贵等等等等，好处只有一个：动态性能是所有液压阀中最高的。就凭着这一个优点，在很多对动态特性要求高的场合不得不使用伺服阀，如飞机火箭的舵机控制、汽轮机调速等等。动态要求低一点的，基本上都是比例阀的天下了。一般说来，好像伺服系统都是闭环控制，比例多用于开环控制；其次比例阀类型要多，有比例压力、流量控制阀等，控制比伺服药灵活一些。从他们内部结构看，伺服阀多是零遮盖，比例阀则有一定的死区，控制精度要低，向应要慢。但从发展趋势看，特别在比例方向流量控制阀和伺服阀方面，两者性能差别逐渐在缩小，另外比例阀的成本比伺服阀要低许多，抗污染能力也强！
这力士乐阀有一个大小6到10,和是一个系列1X或2X。其最大操作压力是5100 PSI或4600 PSI,及其最大流量是7.9 GPM,11.1 GPM(大小6)或37 GPM(10码)。这种阀门熊直接操作比例方向控制阀,控制流体流动的方向和数量。底板安装的模式移植到喧嚣24 340年形成,ISO 4401 - 3,NFPA T3、5、1 D MR1 03,ANSI B 93.7 D 03、05接口。

力士乐REXROTH比例阀 比例方向阀4WRA 阀对流量的控制可以分为两种：
一种是开关控制：要么全开、要么全关，流量要么最大、要么最小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。
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。
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，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。

力士乐电磁溢流阀
溢流阀是一种液压压力控制阀。在液压设备中主要起定压溢流作用，稳压，系统卸荷和安全保护作用。 定压溢流作用：在定量泵节流调节系统中，定量泵提供的是恒定流量。当系统压力增大时，会使流量需求减小。此时溢流阀开启，使多余流量溢回油箱，保证溢流阀进口压力，即泵出口压力恒定（阀口常随压力波动开启）。
稳压作用：溢流阀串联在回油路上，溢流阀产生背压运动部件平稳性增加。
系统卸荷作用：在溢流阀的遥控口串接溢小流量的电磁阀，当电磁铁通电时，溢流阀的遥控口通油箱，此时液压泵卸荷。溢流阀此时作为卸荷阀使用。
安全保护作用：系统正常工作时，阀门关闭。只有负载超过规定的极限（系统压力超过调定压力）时开启溢流，进行过载保护，使系统压力不再增加（通常使溢流阀的调定压力比系统最高工作压力高10%～20%）。
实际应用中一般有：作卸荷阀用，作远程调压阀，作高低压多级控制阀，作顺序阀，用于产生背压（串在回油路上）。
溢流阀一般有两种结构：1、直动型溢流阀 。2、先导型溢流阀。
对溢流阀的主要要求：调压范围大，调压偏差小，压力振摆小，动作灵敏，过载能力大，噪声小。
