德国REXROTH单向阀是用来控制液压系统中油液的流动方向或者调节其压力和流量的，因此它可分为方向阀、压力阀和流量阀三大类。一个外形相同的阀，可以因为作用机制的不同，而具有不同的功能。压力阀和流量阀利用通流截面的节流作用控制着系统的压力和流量，而方向阀则利用通流通道的改换控制着油液的流动方向。这就是说，只管液压阀存在着各种各样不同的类型，它们之间还是保持着一些基本共同之点的。
德国REXROTH单向阀是依靠控制流体压力，可以使单向阀反向流通的阀。这种阀在煤矿机械的液压支护设备中占有较重要的地位。液控单向阀与普通单向阀不同之处是多了一个控制油路K，当控制油路未接通压力油液时，液控单向阀就象普通单向阀一样工作，压力油只从进油口流向出油口，不能反向流动。当控制油路油控制压力输入时，活塞顶杆在压力油作用下向右移动，用顶杆顶开单向阀，使进出油口接通。若出油口大于进油口就能使油液反向流动。
