Thank you for your answer, on Par. 6.2 the norme stated "Reduced-opening valves shall be furnished in the nominal sizes in accordance with Table 1", so in my opinion API 6D cover 1/2" reduced bore ball valve. I accept further discussion about this my interpretation. Thank you in advance to everybody want to give his personal interpretation.
