6014兩位三通緊湊型電磁閥，直動式，通用型，DN 1.5-2.5mm, 0-16 bar, 1/16-5/64, 0-72 psi
6021直動式兩位兩通比例電磁閥，內(nèi)孔0.8 - 1.6 mm
6022直動式兩位兩通比例電磁閥，內(nèi)孔0.8 - 4.0 mm
6023直動式兩位兩通比例電磁閥，內(nèi)孔4.0 or 6.0 m

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(dāng)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(dāng)入口與出口達(dá)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，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。 
特點(diǎn)： 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。

The valve opens. When the inlet and outlet reach the starting pressure difference, when the power is energized, the electromagnetism first pilot small valve, the pressure of the lower cavity of the main valve increases, the upper chamber pressure drops, so that the main valve is pushed up by the pressure difference; When the power is off, the pilot valve USES the spring force or medium pressure to push the closure, moving down and closing the valve.
