1 For DN10 and 15 sizes use DN15 counter (pipe) flanges.
2 The specified torque values are dependent on variables (temperature, bolt material, gasket material, lu-
bricants, etc.) which are not within the control of the manufacturer. Therefore the values should be re-
garded as indicative only.

CAUTION!
• Pressures are applicable at 20 ° C / 68 ° F.
• For higher temperatures, the pressure ratings are as per ASME B16.5.
