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。

Type 2511 ASI cable plug
Type 0255 can be combined with...
• Seat valve, direct-acting
唯有電磁閥是用電磁力作用于密封在電動調節(jié)閥隔磁套管內的鐵芯完成，不存在動密封，所以外漏易堵。
電動閥力矩控制不易，容易產生內漏，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
電磁閥本身結構簡單，價格也低，比起調節(jié)閥等其它種類執(zhí)行器易于安裝維護。
更的是所組成的自控系統(tǒng)簡單得多，價格要低得多。
特點：在真空、負壓、零壓時能正常工作，但通徑般不超過25mm。

 Installation As required, preferably with actuator upright
由于電磁閥是開關信號控制，與工控計算機連接十分方便。
在當今電腦普及，價格大幅下降的時代，電磁閥的就更加明顯。
• Pressure range up to 100 bar
• Media temperature up to 250 °C

外漏堵，內漏易控，使用安全
內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、氣動、液動執(zhí)行機構控制閥芯的轉動或移動。
這都要解決長期動作閥桿動密封的外泄漏難題；
