· 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
Ordering example:
To order a ball valve with ISO5211 standard threaded hole, please add "D" after the original RKH stainless steel ball valve model.
Such as: RKH G3/4 20 4425 D
The valve body is forged, and the length of the screw must be matched when the bracket is installed.
