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

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。

Nominal Ambient Temperature Ranges:

Class F Coils AC: 32°F to 125°F (0°C to 52°C)

Class H Coils AC: 32°F to 140°F (0°C to 59°C)

Class H Coils DC: 32°F to 77°F (0°C to 25°C)

(104°F/40°C occasionally)
