See Optional Features Section for other available options.

它是一種直動和先導式相結合的原理，當入口與出口沒有壓差時，

通電后，電磁力直接把先導小閥和主閥關閉件依次向上提起，閥門打開。

當入口與出口達到啟動壓差時，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；

斷電時，先導閥利用彈簧力或介質壓力推動關閉件，向下移動，使閥門關閉。

Standard Voltages: 24, 120, 240, 480 volts AC, 60 Hz (or 110, 220 volts AC, 50 Hz).

6, 12, 24, 120, 240 volts DC. Must be specified when ordering.

Other voltages available when required.

特點：1.在真空、負壓、零壓時能正常工作，但通徑一般不過25mm。

2.在零壓差或真空、高壓時亦可動作，但功率較大，要求必須水平安裝。

Mounting bracket (suffix MB)

High Vacuum service (suffix VH; see Vacuum Section for more details.)

Oxygen service (suffix N)

Silicone Free (suffix SF)

Elastomers: FKM (suffix V), Ethylene Propylene (suffix E),

CR (suffix J), PTFE* (suffix T), Low Temp. NBR** (suffix A)

Note: *PTFE reduces pressure rating by 25% (i.e. 750 psi reduced to 560 psi)

**For Low Temp. NBR, fluid temperature range is -40°F to 167°F

Refer to Engineering Section for fluid and temperature compatibility.

1）常閉型，通電時電磁線圈產生足夠的電磁力把運動部件（

由磁芯、閥桿、上下部的膜片/密封件構成）從閥座上提起，

閥門開啟；斷電時彈簧力把運動部件壓在閥座上，閥門關閉。

2）常開型，動作方向與常閉型相反。
