这种阀借助于阀的电磁铁,通过手动开关,一个限位关或一个压力继电器进行以电气控制来调节液流方向。备有交流、支流和带整流器的直流电磁铁。
可转换的DC-AC电磁铁是一个直流DC电磁铁带有一个转换器和一个振荡缓冲器,以便使用于交流AC电源。
由一个小尺寸的电磁换向阀和一个靠导阀操纵改变回路中主液流的方向的大尺寸导换向阀组成。
基上上,导阀芯通过通过双电磁铁三位阀中的双弹簧、单电磁铁的单弹簧,双电磁铁两位阀的无弹簧,可被移零位;另一方面,主阀阀芯可由双弹簧移中位,不以中的由无弹簧移动。
夹在导阀和主阀之间的导调节阀调节主阀芯的移动速度,以降低系统中的液压冲击。从导阀电磁铁转换到主阀芯*移位的时间延迟随压力、油粘度及导流量而变化,对导压力来说,不小于5-10kgf/cm2的压力是必要的。
这是一种组合阀,由带四个座阀的主阀、一个用于导控制的电磁换向阀和一个导选择阀组成。主阀和选择阀的各种不同组合为座阀提供各别的方向控制、流量控制或压力控制的功能。
