力士乐Rexroth伺服阀与比例阀的区别
力士乐Rexroth伺服阀
液控伺服阀主要是指电液伺服阀,它在接受电气模拟信号后，相应输出调制的流量和压力。它既是电液转换元件，也是功率放大元件，它能够将小功率的微弱电气输入信号转换为大功率的液压能（流量和压力）输出。在电液伺服系统中，它将电气部分与液压部分连接起来，实现电液信号的转换与液压放大。电液伺服阀是电液伺服系统控制的核心。
力士乐Rexroth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。
