John. You could try putting WD40 on the Stop Cock and leave for a while then see if you can get it to move using a pair of pump pliers. But like already advised if you put too much pressure on it the stem might break or even worse the pipe buckles. So, would suggest you try this when you have turned mains off from the road. If thus does not work then you need to replace it. Bill Pipe Dreams Plumbing Services Bournemouth

Hi john. You might be able to, it depends on how tight it is already. If you tighten it to much you might snap it and end up creating more problems. It might be better to replace it.
