Additional Specifications
For specifications such as materials, port diameters,
valve plug travels, yoke boss diameters, and stem
diameters, refer to the Parts List
1. The pressure or temperature limits in this manual and any applicable standard limitations should not be exceeded.
2. Certain bonnet bolting material selections may require a CL600 easy‐e valve assembly to be derated. Contact your Emerson sales office.
3. There are two different CL900 NPS 8x6 valve bodies, one for use only with Cavitrol III cages and the other for use with all other constructions. A CL900 valve with Cavitrol III cage can take full
CL900 pressure drops. For information on other NPS 8x6 constructions that can take full CL900 pressure drops, contact your Emerson sales office. All other trim constructions are limited to
CL600 pressure/temperature limits even though installed in a CL900 valve.
