美国ASCO防爆电磁阀NFB344A70 110V

防爆电磁阀是把设备可能点燃爆炸性气体混合物的部件全部封闭在一个外壳内，其外壳能够承受通过外壳任何接合面或结构间隙，渗透到外壳内部的可燃性混合物在内部爆炸而不损坏，并且不会引起外部由一种、多种气体或蒸气形成的爆炸性环境的点燃，把可能产生火花、电弧和危险温度的零部件均放入隔爆外壳内，隔爆外壳使设备内部空间与周围的环境隔开。

Selecting and Ordering the Right Valve

To assist in selecting the proper valve for your application,

we recommend two approaches. First, if you know the valve

series that meets your needs, you can go directly to the

appropriate page as listed in the Numerical Listing, or the

Main Index. If you do not know the proper valve Series,

please refer to the Condensed Listing, which provides an

overview of key specifications for all General Service valves

included in this catalog. This listing is organized by valve

type and operation, then indexed by pipe size, flow factor,

and other vital specifications.

If you are unable to locate the desired valve in the Condensed

Listing, refer to the individual valve series in the main catalog

for a more complete listing.

In order to select a valve, you will need the following

application information:

Valve Type 2-Way, 3-Way, 4-Way

Operation Normally Open, Normally Closed, Universal

Pipe Size Pipe size or flow requirement

Media Fluid to be controlled

Pressure Minimum and maximum operating pressure

Temperature Minimum and maximum fluid and ambient

temperature (if unusual, contact technical support)

Voltage Voltage and frequency to be used

Extras Special seals, special seats, brackets, etc.
