【进口分布直动式电磁阀】【介质粘度 50C ST（大于时可定制）】

原理：它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使阀门关闭。　　
特点：在零压差或真空、高压时亦能可*动作，但功率较大，要求必须水平安装。

广泛应用在航天、船舶重工、石油化工、工业炉窑、锅炉、给排水、采暖空调、消防设备、干燥设备

食品医疗设备、清洗设备、景观灌溉、喷泉、水厂等管道系统中.

It is widely used in aerospace, shipbuilding Heavy Industry, petrochemical, industrial furnaces, boilers, plumbing, heating and air conditioning, fire-fighting equipment, drying equipment，Food medical equipment, cleaning equipment, landscape irrigation, fountains, water and other piping systems

☆常闭型：线圈通电时，主阀芯靠介质压差力打开；线圈断电，阀关闭。

☆常开型：线圈通电时，阀关闭；线圈断电，主阀芯靠介质压差力打开。
