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，

Direct Acting General Service Solenoid Valves Brass or Stainless Steel Bodies 1/8" and 1/4" NPT

Nominal Ambient Temperature Ranges: AC:  32˚F to 125˚F (0˚C to 52˚C) AC:  32˚F to 104˚F (0˚C to 40˚C) 

Refer to Engineering Section for details.

当入口与出口达到启动压差时，通电后，电磁力先导小阀，

主阀下腔压力上升，上腔压力下降，

从而利用压差把主阀向上推开；

Refer to Engineering Section for details.

Approvals: CSA certified. UL listed General Purpose Valves. Meets applicable CE directives. 

Refer to Engineering Section for details.

Standard: Watertight, Types 1, 2, 3, 3S, 4, and 4X. Optional: Explosionproof and Watertight,

 Types 3, 3S, 4, 4X, 6, 6P, 7, and 9. (To order, add prefix “EF” to catalog number.) 

See Optional Features Section for other available options.

Features • No minimum operating pressure required. 

• The original 3 way valve design.

直动式电磁阀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。

Standard Coil and Class of Insulation

但通径一般不过25mm。

2.在零压差或真空、高压时亦可动作，但功率较大，要求必须水平安装。

常闭型，通电时电磁线圈产生足够的电磁力把运动部件

（由磁芯、阀杆、上下部的膜片/密封件构成）从阀座上提起，阀门开启；

断电时弹簧力把运动部件压在阀座上，阀门关闭。

• High-speed general service. 

• Simplest valve for basic 3 way piloting operation, only a spring and two moving parts. 

• Moderate flow pilots, smaller control valves and actuators.
