溢流閥的主閥上腔壓力，是由先導(dǎo)閥加于控制的，如果先導(dǎo)閥正常工作，即主閥上腔有先導(dǎo)閥規(guī)定的壓力，則整個溢流閥就會在系統(tǒng)壓力到達(dá)調(diào)定壓力時其主閥口打開一定的開度，一方面能將系統(tǒng)多余流量流回油箱，另一方面又能維持系統(tǒng)的壓力為先導(dǎo)閥的調(diào)定值。

atos阿托斯意大利品牌，是世界的電液元件制造商，具有*的技術(shù)，能通過帶電子器件的集成式液壓元件提高現(xiàn)代化機(jī)器的性能。電磁溢流閥原理上，一般是由先導(dǎo)式溢流閥加上一個2位2通電磁閥組成。這個電磁閥實際上由兩部分組成：2位2通的液壓閥部分，加上一個電磁鐵。2位2通閥是開通，還是關(guān)閉，是由電磁鐵推動閥芯運動來實現(xiàn)的。像樓上朋友講的，有的閥電磁鐵通電時打開，有的閥電磁鐵斷電時打開，（根據(jù)系統(tǒng)要求選擇）。也就是說，電磁閥這里有一條通路一頭與先導(dǎo)溢流閥的某個部位相連，另一頭通過油管與油箱相連。通過操作電磁鐵可以讓先導(dǎo)溢流閥的某個部位或者與油箱相通，或者不與油箱相通。產(chǎn)品型號有：AGAM-20/11/210-IX 230/50/60AC

溢流閥一般分為兩類：1、直動型溢流閥 。2、先導(dǎo)型溢流閥，在實際應(yīng)用中為：作卸荷閥用，作遠(yuǎn)程調(diào)壓閥，作高低壓多級控制閥，作順序閥，用于產(chǎn)生背壓。
