德国力士乐直动式比例减压阀：R900963713 3DREPE6C-2X/45EG24N9K31/A1V现货销售
设置：
阀门的基本构成包括：
功能：
通过比例电磁铁设置 A 或 B 中的压力。压力的大小取决于电流。线圈（5、6）断电后，控制阀芯 (2) 将通过压缩弹簧 (8) 保持在中心位置。油口 A 和 B 连接到 T，以便液压油可以不受阻挡地流入油箱。通过为比例电磁铁（例如线圈“a”(5)）通电，压力测量阀芯 (3) 和控制阀芯 (2) 将向右移动。这样将通过具有渐进流体特性的节流横截面，打开从 P 到 B 及从 A 到 T 的连接。在通道 B 中形成的压力通过压力测量阀芯 (4) 的表面作用于控制阀芯，抵抗线圈磁力。压力测量阀芯 (4) 受线圈“b”支撑。如果压力超过线圈“a”上设置的值，将逆线圈磁力方向回推控制阀芯 (2)，并建立 B 与 T 的连接，直到重新达到调定压力。
压力与线圈电流成比例。当线圈关闭时，控制阀芯 (2) 在压缩弹簧 (8) 的作用下返回到中心位置。可选手动应急操作元件（9、10）可在线圈不通电的情况下移动控制阀芯 (2)。
