For the pneumatic flange ball valve I believe that many friends have the experience of using, but usually may not pay attention to its advantages, then let's introduce the advantages of the pneumatic flange ball valve in detail:
对于气动法兰球阀相信很多朋友都有使用的经历，但是平时可能没有注意它的优点，那么就为大家详细介绍一下气动法兰球阀的优点：
1, pneumatic flange ball valve, according to the requirements of the conditions of use, with soft seal (-30 ~ 180℃) and hard seal (-40 ~ 450℃).
1、气动法兰球阀，根据使用条件的要求，具有软密封（-30～180℃）和硬密封（-40～450℃）。
It can be divided into two types of sealing structures.
它可以分为两种类型的密封结构。
Reasonable use in different media, different temperatures, different pressure positions.
在不同的介质，不同的温度，不同的压力位置合理使用。
2, the pneumatic flange ball valve is driven by gas, does not contact with sparks, theoretically has explosion-proof function, relatively An complete.
2、气动法兰球阀由气体驱动，不与火花接触，理论上具有防爆功能，相对An全。
In addition, if a gas leak occurs, it can be directly discharged, so it will not pollute the environment and is very safe.
另外，如果发生漏气，可以将其直接排放，因此不会污染环境，并且非常An全。
3, due to the role of torque, in terms of the diameter of the valve, manual ball valves can usually only be equipped with a diameter of less than DN300 ball valves, and pneumatic flange ball valves can be configured into a larger diameter range.
3、由于扭矩的作用，就阀的直径而言，手动球阀通常只能配备直径小于DN300的球阀，而气动法兰球阀可以配置成较大的直径范围。
Not only can the small ball valve be installed, but also the large diameter ball valve can be installed, the current large diameter of the pneumatic ball valve is DN1200.
不仅可以安装小径球阀，还可以安装大径球阀，目前气动球阀的大直径为DN1200。
