CO2 Injection Valve replacement

[Old Fat Biker Bloke]

Sorry to post on this topic this again but I've spent a lot of time asking & looking into this but still no concrete answer & I WANT TO START BREWING!!! :

The hole in the top cap of my barrels (Boots & Youngs) look the same; the diameter LOOKS compatible with the valve kits for sale everywhere - surely I can just remove the old valve system and fit new valves to the caps, right???

Thanks!!!

I think their a standard size

I reckon they're all pretty standard - an S30 valve should fit - most homebrew shops will stock them - are you close enough to one to take the barrel caps in and see if they will fit ok??

I bought a s30 valve and cap yesterday from my lhbs ,they are interchangable with the pin type valve by just undoing a nut with an adjustable spanner.
