REXROTH力士乐电液比例控制阀

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zui大、要么zui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。

REXROTH力士乐电液比例控制阀用以改变管道内气体或液体流向的控制元件叫方向控制阀。在实际应用中，可根据不同的需要将方向控制阀分成若干类别：
（1）按照气体在管道的流动方向，如果只允许气体向一个方向流动，这样的阀叫做单向型控制阀，比如单向阀，梭阀等；可以改变气体流向的控制阀叫做换向阀，比如常用的2way2port，2way3port，2way5port，3way5port等。
（2）按照控制方式可分为电磁阀，机械阀，气控阀，人控阀。其中电磁阀又可以分为单和双电控阀两种；机械阀可分为球头阀，滚轮阀等多种；气控阀也可分为单气控和双气控阀；人力阀 可以分为手动阀，脚踏阀两种。
（3）按工作原理可以分为直动阀和先导阀，直动阀就是靠人力或者电磁力，气动力直接实现换向要求的阀；先导阀是由先导头和阀主体2部分构成，有先导头活塞驱动阀主体里面的阀杆实现换向。
（4）根据换向阀杆的工作位置可以将阀分为2way，3way阀。
（5）根据阀上气孔的多少来进行划分，可以分为2port，3port，5port阀。

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zui大、要么zui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。
