Using FCI-70-2 or API-598 - Valve engineering - Eng-Tips

He should use FCI 70-2 for seat leakage tests, for the simple reason that API 598 / API 6D allowable leakages are meant for shut-off valves, therefore much more restrictive than FCI 70-2. Control valves are meant for control, not shut-off. As for the shell test, it's ok to use API 598 / API 6D, since FCI 70-2 doesn't cover such tests.
