6 MARKING

MARKING

ASME B16.34 – MARKING REQUIREMENTS

Name

The Manufacturer’s name or trademark

Materials

Cast valves shall be marked with the heat number or heat identification and symbols (letters and numbers) as given in the ASTM specifications to designate the material grade.

Rating

The valve body shall be marked with the number that corresponds to the pressure rating class designation except the special class, limited class, intermediate rated – standard class and intermediate rated – special class valves may instaed be marked with the valve’s maximum allowable temperature and its associated rated temperature.

Temperature

Temperature markings are not required except as indiacted above.

Size

The NPS designation number shall be shown

Omission of Marking

On valves whose size or sape limits the body markings, they shall be ommited in the following order: a) size b) rating 3) material 4) manufacturer’s name or trademark

Ring Joint Flange

Valves having ring-joint end flanges shall have the edge (periphery) of each ring-joint end flange marked with letter “R” and the corresponding ring-froove number.

Multiple Material MArking

Material for valve bodies, bonnets, and cover plates that meet the requirements for more than one specification or grade of the specification llisted in Table 1 (ASME B16.34 – 2013) may, at the manuufacturer’s option, be marked with more than one of the applicable specification or grade symbols. These identification markings shall be placed to avoid confusions in identification. The acceptabilty of multiple markings shall be in accordance with guidelines set out in ASME Boiler and Pressure Vessel Code, Section ll, Part D, Appendix 7.
