Yes you can repack a valve if the meter is turned off and you don't have
water at 30-40PSI at the bad valve.
If you omit reseating the valve, you will wear out the seals turning the
valve on and off repeatedly. You want to just remove the rough corrosion
inside, where the seal meets the seat.
> (OP): so I should be able to fix the valve

>> First, the meter must be turned off.
>> Second, drain the system. Flushing toilets is not necessary.
>> Third, unscrew the stem nut.
>> Fourth, unscrew the stem from the valve body
>> Fifth, reseat the valve body.
>> Sixth, replace stem, packing, seat seals or entire stem with new seals
>> attached already from new valve. Pitch valve body or use it as a
>> paperweight.
>> Seventh, turn meter back on.
>>
>> Now you wont have an old valve in your system which WILL leak around the
>> stem later or sooner.
>>
>> Miserly : just buying the seals and seating tool (least expensive)
>> buying the new valve and seating tool, removing the stem
>> complete and replacing in old valve body after cleaning the seat.
>> (easiest, fastest, and stem will be stronger)
>> Ballsy : going amongst pros...
