Ball valves applications?

I was doing some reading around different valve types; and came across this page on Fluid Controls. It states
"Widely used in industries from analytical through to offshore, our ball valves range includes miniature ball valves, ball check valves, cyrogenic ball valves, high pressure ball valves, rotary plug valves and swing out ball valves." But, I was just wondering; what other applications could they be used for? I know it says from analytical to offshore - but I'd be curious to learn what other industries you've used ball valves in and why you've chosen them over other types?

As stated ball valves are widely used in a variety of industries; anywhere where liquids or liquors are part of the process.
Perhaps you should consider where they are not used. The water industry has sewage farms where pipework diameters 3M or larger; where gate or butterfly valves are more appropriate. Generally though the type of valve (e.g. the chemical industry) is specified by a Process Engineer.
