al它是一种直动和先导式相结合的原理，当入口

与出口没有压差时，通电后，电磁力直接把先导小

阀和主阀关闭件依次向上提起，阀门打开。当入口与

出口达到启动压差时，通电后，电磁力先导小阀，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.)

阀下腔压力上升，上腔压力下降，从而利用压差把主阀

向上推开；断电时，先导阀利用弹簧力或介质压力推动

关闭件，向下移动，使阀门关闭。

特点：1.在真空、负压、零压时能正常工作，但通径一般不过25mm。

2? Choice of metal seating materials to handle aggressive

fluids, or resilient seating for airtight shutoff.

? Ideal for power.在零压差或真空、高压时亦可动作，但功率较大，要求必须水IM电竞装。
