双向电磁阀特点
1、该阀采用不锈钢活塞密封，*杜绝泄露产生；

2、在使用压力范围内，该阀不分进口和出口，即进口当出口，出口当进口都可以正常使用；

3、线圈采用大功率线圈，保证双向电磁阀的迅速打开和关闭；

4、内部采用特殊加工304不锈钢弹簧，使介质从出口流向进口的时候，也能*关闭；

5、该阀采用直动式结构，满足使用压力很低的工况。
双向电磁阀（低压型）工作原理
常闭：双向电磁阀平时处于关闭状态；当线圈通电之后，电磁阀打开，断电后，电磁阀关闭。电磁阀处于开启状态的时候，进口压力大于出口压力，介质由进口端流向出口端；当出口压力大于进口压力，介质由出口端流向进口端。并且不管介质压力是进口端大于出口端，还是出口端大于进口端，电磁阀在断电之后，都能截止介质。
先导式双向电磁阀的结构
先导式双向电磁阀主要由阀体、常闭主阀瓣、常开主阀瓣、先导阀瓣、电磁铁等零部件组成。主阀瓣和活塞之间通过顶杆相连（图1），其特点是内部无弹簧等弹性复位元件，*靠气动力和电磁力切换各气路通道，控制常开腔和常闭腔供气和密封，工作压力5.0MPa。

当电磁铁处于断电状态时，进口气体分为两路，一路直接作用于常开主阀瓣上使其打开，电磁阀常开腔B供气，另外一路作用于先导阀瓣上，并沿气体通道进入常闭控制腔F内，使常闭主阀瓣密封。当电磁铁通电后，先导阀瓣关闭，常闭控制腔F内气体从放气口D排入大气，常闭控制腔F泄压，常闭主阀瓣开启，电磁阀常闭腔C供气，同时气体也会沿气体通道进入到常开控制腔E内，将常开主阀瓣压紧密封。
