Suggest to follow ASME FFS-1/API 579-1 for detail assessement...
In my personal opinion, there will be high risk to repair valve for the said application...
Kind regards,

Dear Mr.Marcelo P. Soriano,
Thanks for your mail.
I understaood the situation.I am not telling to use as it is..
Take more care.Do repair.Pls ensure that the defect is removed.
Then you can use.
Getting new valve will take months.Also will cost more money.
Everyone cannot do the repair and it is not a easy task.but it is possible.
.Some expert guidance required.
