difference between reduced bore valves and full bore valves

Dear All,
I'am going to buy a ball valve for oi processing system, but wonder between reduced bore ball valve and full bore ball valve. any one with solution please provide an answer.

Well reduced bore increases the pressure drop across the valve as compared to full bore ball valve. It also depends on the system, the allowable pressure drop.

thank all

Just to add simple point:
Full bore valve that's mean the valve bore equal to the valve size; for example if you have 1" full bore valve this mean valve bore equal to 1":sneakiness:Thanks a lot
