二位三通座阀式换向阀
概述
M-.SED型换向阀是电磁驱动的直动式座阀换向阀，用于控制流动的启动、停止及方向，主要由阀体（1）、电磁铁（2）、阀座（7）、（11）以及关闭元件（4）组成。
手动应急操作（6）可在电磁铁未通电时切换阀。
基本原理
阀的初始状态为常开UK或常闭CK，由弹簧（5）的布置决定。关闭元件（4）后方的腔室（3）与P口相连，并与另一油口密封隔离；
T。因此，阀相对于操作力（电磁铁力和弹簧力）实现压力平衡。
采用特殊关闭元件（4），P、A、T口均可承受350 bar最高工作压力，油液也可双向流动，参见符号！
初始位置时，关闭元件（4）由弹簧（5）压在阀座（11）上；切换后，则由电磁铁（2）压在阀座（7）上，流路无泄漏地截止。
在二位三通座阀式换向阀下方安装Plus-1叠加板，可实现二位四通座阀式换向阀功能。
Plus-1 叠加板的功能
初始位置：
主阀未动作时，弹簧（5）使关闭元件（4）压在阀座（11）上，P口封闭，A与T相通。另有控制管路从A连接至控制阀芯（8）的大端面，使其向油箱卸压。P口压力将球（9）压向阀座（10），因此P与B相通，A与T相通。
过渡位置：
主阀动作时，关闭元件（4）克服弹簧（5）移向阀座（7）并压紧。过程中T口封闭，而P、A、B会短暂互通。
切换位置：
P 与 A 连通。泵压经 A 口作用于控制阀芯（8）的大面积上，将钢球（9）压在阀座（12）上，从而使 B 与 T 连通、P 与 A 连通。Plus-1 叠加板中的钢球（9）具有“正遮盖”。
