力士乐4WREE6W32-24/G24K31/A1V比例方向阀

力士乐4WREE6W32-24/G24K31/A1V比例方向阀；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{zd0}、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。
