6 Design6.1 Pressure and temperature ratingThe n omina l pressure (PN) class or the ANSI rating class shall be used for the specification of the required press ureclass.Valves covered by this International Standard should be furnished in one of the following classes:
PN 20 (Class 150) PN 150 (Class 900)PN 50 (Class 300) PN 250 (Class 1500)PN 64 (Class 400) PN 420 (Class 2500)PN 100 (Class 600)
Pressure classes shall be specified by the p urchase r in accorda nce with the applicab le rating tables for materialgroups in ASME B16.34.
The purchaser may specify intermediate design pressures and temperatures for his specific application.Allowab le operating pressures and tempe ratures for valves made of materials not cove red by AS ME B1 6.3 4 shallbe determ ined by calculations in accordance with an agree d pressure vessel design stan dard, such as ASM ESection VIII, D ivision 1 and Division 2, or BS 5500.Non -metallic parts may limit minimum and maximum operating pressures and temperatures.The maximum operating pressure at the minimum and maximum operating temperatures shall be marked on thenameplate.
