Notes : Pour les robinets-vannes à bride, la pression de service maximale doit être limitée selon la valeur la plus faible entre la classe du corps et la classe de la bride.
Pour les robinets-vannes BW, la pression doit être limitée conformément à la pression nominale de l’écrou-union : - PN 63 pour DN 08- PN 40 pour DN 12 et DN 15- PN 25 pour DN 20 et DN 25
For flanged valves, the maximum operating pressure must be limited according to the lowest value between body rating and flange rating.
For BW valves, pressure must be limited according to union-ring PN: - PN 63 for DN 08- PN 40 for DN 12 and DN 15- PN 25 for DN 20 and DN 25
