宝德导控制带伺服活塞电磁阀/进口BURKERT电磁阀
宝德导控制带伺服活塞电磁阀采用次开阀和二次开阀连在体，主阀和导阀分步使电磁力和压差直接开启主阀口。当线圈通电时，产生电磁力使动铁芯和静铁芯吸合，导阀口开启而导阀口设在主阀口上，且动铁芯与主阀芯连在起，此时主阀上腔的压力通过导阀口卸荷，在压力差和电磁力的同时作用下使主阀芯向上运动，开启主阀介质流通。当线圈断电时电磁力消失，此时动铁芯在自重和弹簧力的作用下关闭导阀孔，此时介质在平衡孔中进入主阀芯上腔，使上腔压力升高，此时在弹簧复位和压力的作用下关闭主阀，介质断流。结构合理，动作可靠，在零压差时工作也可靠。如：ZQDF，ZS，2W等。宝德导控制带伺服活塞电磁阀由导阀和主阀芯着形成通道组合而成；常闭型在未通电时，呈关闭状态。当线圈通电时，产生的磁力使动铁芯和静铁芯吸合，导阀口打开，介质流向出口，此时主阀芯上腔压力减少，低于进口侧的压力，形成压差克服弹簧阻力而随之向上运动，达到开启主阀口的目的，介质流通。当线圈断电时，磁力消失，动铁芯在弹簧力作用下复位关闭导口，此时介质从平衡孔流入，主阀芯上腔压力增大，并在弹簧力的作用下向下运动，关闭主阀口。
