日本CKD是是日本CKD株式会社投资的气动公司，主要制造气源处理三大件、气缸、电磁阀等自动化产品。CKD主要生产的产品有自动化机械（灯管制造，CCFL,LED制造设备，药品泡壳包装设备，二次电池卷绕机，三维焊锡印刷基板检查仪）；气动控制系统（FRL气源处理件，气动换向阀，气缸以及其他附件）；流体控制系统（多介质电磁阀，气控阀，马达阀，分析仪器阀，切削液控制阀，高真空阀，煤气天然气LPG阀，高纯化学液体阀，工艺气体阀）以及省力系统（DD-MOTOR,间隙式转台）。
*AB42-02-7-02E电磁阀是用来控制遥控复位气缸进气，在超速遮断滑阀复位前，四通电磁阀是切断的。为使超速遮断滑阀复位，把电磁阀通电，使气缸的一端输入压缩空气控制，另一端排大气，当空气进入气缸时，推动活塞与连杆，因而使杠杆旋转，开半闭超速遮断滑阀，当快速限位开关动作时，说明活塞已达其行程终点，超速遮断滑阀即行复位，随后电磁阀切断电源，空气进入气缸的另一端，使活塞重新返回原位。“复位—遮断”手柄也回到“正常”位置，此后，只要滑阀仍旧关闭，手柄就一直保持在此位置不变。
