费斯托FESTO比例调压阀：直动式电磁阀：原理：通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。特点：在真空、负压、零压时能正常工作，但通径一般不超过25mm。

费斯托比例调压阀VPPM-8L-L-1-G14-0L10H-V1P-S1C：费斯托先导式电磁阀：原理：通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关闭件周围形成上低下高的压差，流体压力推动关闭件向上移动，阀门打开；断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差，流体压力推动关闭件向下移动，关闭阀门。特点：流体压力范围上限较高，可任意安装（需定制）但必须满足流体压差条件。电磁阀从阀结构和材料上的不同与原理上的区别，分为六个分支小类：直动膜片结构、分步直动膜片结构、先导膜片结构、直动活塞结构、分步直动活塞结构、先导活塞结构。
