· Welded ball valve
Add “W-” to the ball valve type to indicate the welded interface
(see table below), for example: W-BKH 20S×2 16 11251, “×2” means
the welded joint wall thickness S is 2.
·Sleeve type connected ball valve
Add "C-" to the ball valve model to indicate the card sleeve
interface (see table below), eg C-BKH 20S 16 11251
