king keg valve

[johnson1985]

Hi, we have a king keg filled with 25 litres of cider and are looking to force carbonate it. However, the valve is an old one, so we need to buy a new valve and some c02 canisters. Is an s30 valve a good idea? If so, where can we get some co2 that fits that valve?

Any help would be much appreciated!
