REXROTH力士樂燃氣電磁閥4WE10D33/CG24N9K4價格 

力士樂電磁閥的特點：在真空、負壓、零壓時能正常工作，但通徑一般不超過25mm。
Rexroth分布直動式電磁閥原理：它是一種直動和先導(dǎo)式相結(jié)合的原理，當入口與出口沒有壓差時，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。當入口與出口達到啟動壓差時，通電后，電磁力先導(dǎo)小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時，力士樂先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動關(guān)閉件，向下移動，使閥門關(guān)閉。
   Rexroth電磁閥特點：在零壓差或真空、高壓時亦能可*動作，但功率較大，要求必須水平安裝。REXROTH力士樂燃氣電磁閥4WE10D33/CG24N9K4價格 
力士樂先導(dǎo)式電磁閥原理：通電時，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān)閉件周圍形成上低下高的壓差，流體壓力推動關(guān)閉件向上移動，閥門打開；斷電時，Rexroth電磁閥彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，Rexroth電磁閥流體壓力推動關(guān)閉件向下移動，關(guān)閉閥門。
