What is the primary advantage of a 'full port' (full bore) ball valve over a 'standard port' (reduced bore) ball valve?
Select your answer
A
Full port valves have higher pressure ratings
B
Full port valves have a bore equal to the pipe ID, allowing pigging, full flow, and minimal pressure drop; standard port has a reduced bore that increases velocity and pressure drop
C
Full port valves are always less expensive
D
Full port valves can be used for throttling; standard port cannot
