美标铸钢法兰闸阀在管路中主要用来做切断速度快、分配和改变介质的流动方向。美标铸钢法兰闸阀是一种新型阀门，它具有以下优点：

American Standard cast steel flanged gate valve in the pipeline is mainly used to make the flow direction of the cutting speed, distribution and change of medium. American Standard cast steel flanged gate valve is a new type of valve, it has the following advantages:

1． 流体阻力小，其阻力系数与同长度的管段相等。

1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.

2． 结构简单、体积小、重量轻。

2., simple structure, small size, light weight.

3． 紧密可靠，球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。

3., reliable and reliable, ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.

4． 操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。

4. easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.

5． 维修方便，美标铸钢法兰闸阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。

5. convenient maintenance, American Standard cast steel flanged gate valve has the advantages of simple structure, seals are generally activities, removal of the replacement is more convenient.

6． 在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。

6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.

7． 适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。

7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.

8. 因为美标铸钢法兰闸阀动力源采用的是气体，一般为0.2-0.8MPa压力，相对比较安全。美标铸钢法兰闸阀如果漏气的话，相对液动、电动来说，气体可以直接排出，对环境没有污染，同时具有较高的安全性。

8. because of the American Standard cast steel flanged gate valve power source is gas, the pressure is generally 0.2-0.8MPa, relatively safe. American Standard cast steel flanged gate valve if the leak, the relative hydraulic, electric, gas can be directly discharged, no pollution to the environment, but also has high security.

9.相对于手动和涡轮转动球阀来说，美标铸钢法兰闸阀可以大口径配置，（手动和涡轮转动球阀一般都在DN300口径以下，美标铸钢法兰闸阀可以达到DN1200口径。）

9. compared with the manual and the turbine rotating ball valve, cast steel flanged gate valve can American Standard large aperture configuration (manual and turbine rotating ball valve is generally in the DN300 caliber, American Standard cast steel flanged gate valve can reach DN1200 caliber.)
