al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

CSA certified. Meets applicable CE directives.

Construction

Standard: Red-Hat II - Watertight, Types 1, 2, 3, 3S, 4, and 4X; Red-Hat - Type 1.

Optional: Red-Hat II - Explosionproof and Watertight, Types 3, 3S, 4, 4X, 6,

6P, 7, and 9; Red-Hat - Explosionproof and Watertight, Types 3, 4,

4X, 7, and 9. See footnote on next page.

(To order, add prefix “EF” to catalog number.)

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：1.在真空、負(fù)壓、零壓時能正常工作，但通徑一般不過25mm。

2? Choice of metal seating materials to handle aggressive

fluids, or resilient seating for airtight shutoff.

? Ideal for power.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。
