首先从称号上就能够晓得，他们都是用电动执行器来驱动。从物理构造上说，球阀和蝶阀的构造原理是完全不同，电动蝶阀的启闭件是一块蝶板，而球阀望文生义用的是一个球芯作为启闭件的。

由于球阀运用的是一个球芯，所以工艺能够做的很精致，所以口径相对蝶阀来说能够做到更小，这是球阀的优势，但是球阀的球芯做出大口径对本钱与工艺请求较高，所以同样这也是球阀的优势。相对球阀，蝶阀能够纵情发挥他的优势，把启闭件做到很大。

但是球阀的一个大的优势还是他的密封性相比蝶阀更好。球阀能够接受住高压。但是由于球阀的构造关系与球芯资料是实心的，所以耗费的资料本钱要比蝶阀多，价钱相比照蝶阀更高了。所以选择电动球阀还是电动蝶阀—定是依据本人实践应用中的需求来的，在二者中寻求更合理和经济的。

First of all, it can be known from the title that they are driven by electric actuators. In terms of physical structure, the construction principle of ball valve and butterfly valve is completely different, the opening and closing part of the electric butterfly valve is a butterfly plate, and the ball valve uses a ball core as the opening and closing part.

Because the ball valve uses a ball core, the process can be very refined, so the caliber can be smaller than the butterfly valve, which is the advantage of the ball valve, but the ball core of the ball valve to make a large caliber on the cost and process requirements are higher, so this is also the advantage of the ball valve. Compared with the ball valve, the butterfly valve can give full play to its advantages and make the opening and closing parts very large.

But a big advantage of the ball valve is that its sealing is better than that of the butterfly valve. Ball valve can accept high pressure. However, because the structure of the ball valve and the ball core data are solid, the data cost is more than that of the butterfly valve, and the price is higher than that of the butterfly valve. Therefore, the choice of electric ball valve or electric butterfly valve - must be based on the needs of my practical application, in the two to seek more reasonable and economic.
