Dear jop and all,
Finally I got answer from one of my boss,
Actually the ball valve has to come first, then globe valve.
Reason 1. Globe valve is suspect for leakage so it come second,
Reason 2. Ball valve easy to operate even in high pressure when we compare with globe valve, so the ball it come first.
