al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

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。
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? 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。
