BURKERT电磁阀同时依靠介质压力，主副阀得以紧密关闭。常开电磁阀，线圈通电后由于吸力作用，动铁芯下移，把副阀阀塞压下，副阀关闭，主阀阀杯内压力上升，当压力升到一定值时，主阀阀杯的上下压差一样，由于电磁力作用，动铁芯推动主阀阀杯下，压紧主阀阀座，阀门关闭。线圈断电时，电磁吸力为零，副阀阀塞和动铁芯由于弹簧作用向上提起，副阀打开，主阀阀杯上的流体经副阀流走，减少了作用在主阀阀杯上的压力，当主阀阀杯上的压力减少到一定值时，利用压差把主阀阀杯推起，主阀打开，介质流通。
Baode 5404 solenoid valve
The BURKERT solenoid valve also relies on medium pressure and the main auxiliary valve is closed tightly. Normally open solenoid valve and coil electricity due to the suction effect, after moving iron core down, the deputy valve plug pressure, the deputy valve closed, pressure rise within the main valve cup, when the pressure rises to a certain value, the main valve cup of fluctuation pressure difference, due to the electromagnetic effect, promote the main valve cup of moving iron core, the pressure the main valve seat, the valve closed. Coil power, electromagnetic suction is zero, the deputy valve plug and due to the spring action of moving iron core lift, vice valve is opened, the fluid by the deputy valve on the main valve cup run, reduce the pressure effect on the main valve cup, when the main valve cup pressure was reduced to a certain value, the use of differential pressure push the main valve cup, the main valve opens, medium circulation.

BURKERT电磁阀适用性◇管路中的流体必须和选用的电磁阀系列型号中标定的介质*。
◇流体温度必须小于选用电磁阀的标定温度。
◇BURKERT电磁阀允许液体粘度一般在20CST以下，大于20CST应注明
BURKERT电磁阀该阀采用一次开阀和二次开阀连在一体，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与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。
