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 the NPS 2.

1. Refer to Ordering Matrix for 8560 Valves. For selection temperatures not shown above, contact your Emerson sales office or Local Business Partner.
2. For component selection and applicable fire‐tested standards and codes, consult your Emerson sales office or Local Business Partner.
1. Install a three‐valve bypass around the control valve assembly if continuous operation is necessary during
inspection and maintenance of the valve.
2. Inspect the valve to be certain that it is free of foreign material.
CAUTION
Be certain that adjacent pipelines are free of any foreign material, such as pipe scale or welding slag, that could damage the
valve sealing surfaces.
