CKD电磁阀可以配合不同的电路来实现预期的控制，而控制的精度和灵活性都能够保证。日本CKD喜开理电磁阀有很多种，不同的电磁阀在控制系统的不同位置发挥作用，zui常用的是单向阀、安全阀、方向控制阀、速度调节阀等。
CKD电磁阀从阀结构和材料上的不同与原理上的区别，分为六个分支小类：直动膜片结构、分步直动膜片结构、先导膜片结构、直动活塞结构、分步直动活塞结构、先导活塞结构。
CKD电磁阀原理：电磁阀里有密闭的腔，在不同位置开有通孔，每个孔连接不同的油管，腔中间是活塞，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来开启或关闭不同的排油孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油缸的活塞，活塞又带动活塞杆，活塞杆带动机械装置。这样通过控制电磁铁的电流通断就控制了机械运动。
CKD电磁阀CVSE2-20A-05-B2HS-3是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。
