斷電時(shí)，先導閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門(mén)關(guān)閉。

特點(diǎn)：1.在真空、負壓、零壓時(shí)能正常工作，

Direct Acting General Service Solenoid Valves Brass or Stainless Steel Bodies 1/8" and 1/4" NPT

Nominal Ambient Temperature Ranges: AC:  32?F to 125?F (0?C to 52?C) AC:  32?F to 104?F (0?C to 40?C) 

Refer to Engineering Section for details.

當入口與出口達到啟動(dòng)壓差時(shí)，通電后，電磁力先導小閥，

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(kāi)；

Features ? No minimum operating pressure required. 

? The original 3 way valve design.

直動(dòng)式電磁閥是一種直動(dòng)和先導式相結合的原理，

當入口與出口沒(méi)有壓差時(shí)，通電后，

電磁力直接把先導小閥和主閥關(guān)閉件依次向上提起，閥門(mén)打開(kāi)。

Standard Coil and Class of Insulation

但通徑一般不過(guò)25mm。

2.在零壓差或真空、高壓時(shí)亦可動(dòng)作，但功率較大，要求必須水平安裝。

常閉型，通電時(shí)電磁線(xiàn)圈產(chǎn)生足夠的電磁力把運動(dòng)部件

（由磁芯、閥桿、上下部的膜片/密封件構成）從閥座上提起，閥門(mén)開(kāi)啟；

斷電時(shí)彈簧力把運動(dòng)部件壓在閥座上，閥門(mén)關(guān)閉。

? High-speed general service. 

? Simplest valve for basic 3 way piloting operation, only a spring and two moving parts. 

? Moderate flow pilots, smaller control valves and actuators.
