Depends what's seized. If it's the operating arm(most likely) you might be able to free it off with some penetrating fluid (eg Plusgas) and then lubricate it.

If it's the actual valve itself you'll need to dismantle it and lubricate with red jelly - or if there internal corrosion probably better to replace.

More than likely if its like they usually are just spray the hinge both sides with wd40 or similar and grab it at the end of the spring and work it up and down till it returns itself up
