WARNING
For lugged valve bodies with threaded line bolt holes, personal injury and property damage could result from sudden
release of process pressure if line bolts are not properly installed. To ensure proper line bolt thread engagement, line studs
must be centered in the threaded section of the valve body so that each stud has equal thread engagement in the body. See
figure 5.
8. After centering the valve body, first lubricate and then install the remaining line flange bolting to secure the valve in
the pipeline. Tighten the nuts to the line flange studs in a crisscross pattern to ensure proper alignment of valve,
gaskets, and flanges.
WARNING
A CL600 Control-Disk valve body is not necessarily grounded when installed in a pipeline. If the valve is used in a flammable
or hazardous atmosphere or for oxygen service, an explosion could result due to a discharge of static electricity from the
valve components. To avoid personal injury or property damage, always make sure the valve body is grounded to the
pipeline before putting the control valve assembly into operation in a flammable or hazardous atmosphere.
Note
Standard packings for the CL600 Control-Disk valve are composed of all conductive packing rings (graphite ribbon packing) or
partially conductive packing rings (such as a carbon‐filled PTFE female adaptor with PTFE V‐ring packing) to electrically bond the
