原理：通電時(shí)，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開；
斷電時(shí)，電磁力消失，彈簧把關(guān)閉件壓在閥座上，閥門關(guān)閉。

• Seat valve, direct-acting
唯有電磁閥是用電磁力作用于密封在電動(dòng)調(diào)節(jié)閥隔磁套管內(nèi)的鐵芯完成，不存在動(dòng)密封，所以外漏易堵。
電動(dòng)閥力矩控制不易，容易產(chǎn)生內(nèi)漏，甚拉斷閥桿頭部；
The direct-acting plunger solenoid valve Type 0255 is also suitable for high pressures and high temperatures.
Type 2508 Cable plug
電磁閥本身結(jié)構(gòu)簡(jiǎn)單，價(jià)格也低，比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。
更的是所組成的自控系統(tǒng)簡(jiǎn)單得多，價(jià)格要低得多。
特點(diǎn)：在真空、負(fù)壓、零壓時(shí)能正常工作，但通徑般不超過(guò)25mm。

所以，電磁閥使用特別安全，尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。

由于電磁閥是開關(guān)信號(hào)控制，與工控計(jì)算機(jī)連接十分方便。
在當(dāng)今電腦普及，價(jià)格大幅下降的時(shí)代，電磁閥的就更加明顯。

外漏堵，內(nèi)漏易控，使用安全
內(nèi)外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出，由電動(dòng)、氣動(dòng)、液動(dòng)執(zhí)行機(jī)構(gòu)控制閥芯的轉(zhuǎn)動(dòng)或移動(dòng)。
這都要解決長(zhǎng)期動(dòng)作閥桿動(dòng)密封的外泄漏難題；
