費斯托FESTO比例調壓閥：直動式電磁閥：原理：通電時，電磁線圈產生電磁力把關閉件從閥座上提起，閥門打開；斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉。特點：在真空、負壓、零壓時能正常工作，但通徑一般不超過25mm。

費斯托比例調壓閥VPPM-8L-L-1-G14-0L10H-V1P-S1C：費斯托先導式電磁閥：原理：通電時，電磁力把先導孔打開，上腔室壓力迅速下降，在關閉件周圍形成上低下高的壓差，流體壓力推動關閉件向上移動，閥門打開；斷電時，彈簧力把先導孔關閉，入口壓力通過旁通孔迅速腔室在關閥件周圍形成下低上高的壓差，流體壓力推動關閉件向下移動，關閉閥門。特點：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。電磁閥從閥結構和材料上的不同與原理上的區(qū)別，分為六個分支小類：直動膜片結構、分步直動膜片結構、先導膜片結構、直動活塞結構、分步直動活塞結構、先導活塞結構。
