1. M35-1 and CW2M valve material are not included in ASME B16.34 pressure/ temperature ratings. The designations 150 and 300 for this valve material are used only to indicate relative pres ­
sure/retaining capabilities and are not ASME pressure/ temperature rated classes.
2. CL600 is only available in NPS 2.
