力士乐WH系列控换向阀是用压力油推动换向，实现液流的通断和流动方向的换向阀，实现液流的通断和流动方向的改变，器原理和结构域WEH型电磁阀基本相似，试试去掉其先导电磁阀部分，增加与主阀两端弹簧腔相同的控制盖板即可。
力士乐WEH/WH型换向阀主阀可采用弹簧对中和复位或液压对中和复位：带或不带时间调节器，带或不带主阀行程调节器；主阀内可装预压阀；插入式阻尼器；控制压力超过25MPa时可安装定比例减压阀。
WEH型换向阀的导阀可采用直流或交流电磁铁；带或不带检查按钮；单独式或集中式电气连接形式。
这类阀主阀体采用铸造内流道，压力损失小，通流能力强，比国内相同通径的阀所通过的流量大近2倍，压力高，体积小，可靠性强，品种规格齐全（除19种标准机能外，还可由三位阀变成28种二位阀）
