(OP)
For automatic on-off valve(ball valve), should I test seat leakage according to standard ANSI FCI 70-2(similar with Globe control valve) or API-598 (similar to all type manual valves)

The leakage rate for metal seated ball valves within API STD 598 is similar to ANSI/FCI 70-2. API 598 requires zero bubbles per minute seat leakage for resilient seated isolation valves. Some manufacturers of triple offset butterfly valves offer the resilient seated specifications.
