1. Should we fix inside land 2t min [BWE ID to valve bore transition] for BWE valve, is there any standard requirement. In B16.25 except Fig 2a, Fig 4 other has 13mm min & 5mm min[Fig5&6] land dimensions, difficult to fix 2t in small size valves.
2. What is the difference between Fig2a & Fig4, can we supply Fig2a for Fig4 requirements please
