Plumbing Help

Hi,
I need a ball valve to fit onto my 22mm overflow pipe. Toolstation have three different ones - two are 'push fit' the third is John Guest. The prices all vary. Links below

Questions:

1) will they all work with solvent weld over flow pipe?
2) why the price difference, will the cheapest work fine? I need 15 of them so cheap is good!

Cheapest pushfit

expensive push fit

even more expensive John Guest

Thanks!
