DR…50B型50系列压力控制阀是先导式减压阀，用于系统减压。

这种减压阀由主阀体及主阀芯和带压力设定件的先导阀构成。

停止时阀开启，即油从油路B经过主阀芯流向油路A，A腔压力作用在主阀芯底部。同时来自油路A的压力经主阀芯节流孔并通过孔，作用在先导阀的球形阀芯上。根据弹簧的设定值，在球形阀芯前、油路和弹簧腔建立起压力，控制阀芯在开启位置。油可以**地从B流向A，直到A腔压力超过弹簧的设定压力，阀芯打开。控制阀芯移动到关闭位置与A腔压力与弹簧到达平衡时，就打到了要求的减圧圧力。

控制油总是有弹簧腔经油口外泄油。

单向阀用了使油流从油路A**的流回到油路B。

压力表接口用来连接压力表以检测A口二次压力。
