Why are butterfly valves chosen over ball valves for industrial remote water meters?

But butterfly valves are also chosen as supporting components for large-diameter remote water meters. What are the advantages of doing this? Why not use ball valves, which are cheaper? In fact, large-diameter remote reading water meters can also be used in conjunction with ball valves. The reason why more people choose butterfly valves is that industrial water projects have high requirements regarding the service life and stability of pipelines and equipment. Although ball valves are cheaper, the various problems associated with them are unacceptable for such projects. It turns out that the structure of ball valves makes them highly prone to clogging and scaling. In everyday household use, the issue isn’t as noticeable because water used at home goes through multiple filtration stages. However, industrial water often doesn’t undergo such rigorous filtration, resulting in higher levels of impurities. Therefore, when ball valves are used with industrial water, they frequently experience problems such as blockages and scaling, which prevent the valves from opening or closing properly; this leads to losses for the water supply authorities as well as increased difficulties in maintenance. But butterfly valves do not have this drawback at all. Moreover, their service life is much longer than that of ball valves; therefore, butterfly valves are more suitable as components for remote water meters in industrial water systems.
You actually say that ball valves have a lower cost? This is the first time I’ve heard of it
Me too. I remember that butterfly valves are simple but have poor sealing performance.
The space in the valve chamber is limited, and butterfly valves take up little space.
To be honest, ball valves aren’t cheap. Ball valves also come in various structures, such as fixed-ball and floating-ball types, and butterfly valves have high leakage rates.
Well, ball valves do indeed cost more than butterfly valves; there was an error in that statement. Thank you all for pointing it out
You got it wrong both times; if you don’t know, don’t just make things up. Ball valves are more expensive than butterfly valves for large diameters, while their prices are similar for small diameters. Additionally, ball valves can certainly be used for industrial water; for example, V-ball valves are used in such cases. O-ball valves are commonly used for water that is not too dirty.
