四通电磁阀在我们的生产中应用很多，其工作原理如下： 当有电流通过线圈时，产生励磁作用，固定铁芯吸合动铁芯，动铁芯带动滑阀芯并压缩弹簧，改变了滑阀芯的位置，从而改变了流体的方向。当线圈失电时，依靠弹簧的弹力推动滑阀芯，顶回动铁芯，使流体按原来的方向流动。在我们制氧生产中，分子筛切换系统强制阀的开关就是通过二位四通电磁阀来控制的，气流分别供至强制阀的活塞两端。从而来控制强制阀的启闭。

Four-way solenoid valve in a lot of our production applications, it works as follows: When the current through the coil, the produces excitation effect, pull the fixed iron core moving core, moving core and the compression spring pulls the sliding spool, changing the position of the sliding spool, thus changing the flow direction. When the circuit is power off, relying on spring will push the sliding spool back to moving core, so that the direction of fluid flow according to the original. In our oxygen production, molecular switching system, switching valve is forced through two four-way solenoid valve to control, gas flow is provided to force the valve piston ends. To force the valve to control the opening and closing.
