R983030727
三位四通、二位四通或二位三通型式。
油口布置符合DIN 24340 A型，不带定位孔。
油口布置符合ISO 4401-03-02-0-05，带定位孔。
驱动方式：手柄。
感应式位置开关及接近传感器，非接触检测。
WM..型阀为机械、手动驱动的滑阀换向阀，控制液流的启动、停止及方向。主要由阀体（1）、手柄式驱动装置（2）、控制阀芯（3）及一个或两个复位弹簧（4）组成。未操作时，复位弹簧（4）使控制阀芯（3）保持中位或起始位置；控制阀芯通过驱动装置（2）移至所需阀位。
定位机构
采用旋钮操作的换向阀通常带定位机构。手柄操作的换向阀可选用带定位机构的二位或三位结构。滚轮柱塞操作的换向阀通常不带定位机构。对于带定位机构的操作方式，可根据阀型将阀芯锁定在相应位置。
节流插芯。
若运行条件导致切换过程中可能出现超过阀性能极限的流量，则必须使用节流插芯；插芯安装于换向阀P通道。
