诺冠NORGREN溢流阀型号R17-801-RGLA
NORGREN溢流阀的设定压力由与输入电信号成比例的电磁力决定。当输入一电信号给比例电磁铁时，比例电磁铁将输出相应的电磁力推动先导阀中的针阀。来自系统的压力也作用于针阀上并与电磁力相平衡，如果系统压力升高而超过对应着的电磁力设定值，先导阀中的针阀打开系统压力将回复至设定值。从而系统压力基本上保持恒定。由于比例电磁铁的推力是一定的，所以不同压力等级要通过改变阀座孔径来获得。而不象普通溢流阀那样靠更换不同刚度的调节弹簧来得到。
NORGREN溢流阀右端有一阻尼活塞3（阻尼活塞一方面在锥阀开启或闭合时起阻尼作用，用来提高锥阀工作的稳定性；另一方面用来保证锥阀开启后不会倾斜）。进口的压力油（压力为P）可以由此活塞的径向间隙进入活塞底部，形成一个向左的液压力F=P稟（A为活塞底部面积）。当作用在底部的液压力F大于弹簧力时，锥阀阀口打开，油液由锥阀口经回流口溢回油箱。只要阀口打开，有油液流经溢流阀，溢流阀入口的压力就基本保持恒定。
