D For CL150 metal bearings, three piece assemblies: Metal bearings for CL150 valves are an assembly made up of
three parts: disc spacer, bearing, and bearing spacer (keys 13, 6, and 7) as shown in the orientation of
bearing/spacer tab shown in figure 10.
a. Install the bearing spacer (key 13) into the bearing bore.
b. Install the bearing into the bearing bore until the bearing is flush with the valve body bore.
c. When installing the disc spacer (key 7) position the curved side to match the valve body bore, and position it with
the tab on the spacer pointing away from the disc stop as shown in figure 10.
Note
The disc spacer will have to be held in place when installing the disc and inserting the shaft through the valve body, bearings,
bearing spacer, and disc. To help hold the spacer in place, apply lubricant.
2. Position the disc to be certain that the holes in the disc are towards the actuator side of the valve. Carefully insert
the disc into the valve body bore while protecting the disc sealing surfaces.
3. Install the shaft (key 8):
D For PEEK/PTFE CL150 and CL300 metal bearings, one piece bearings: Slide the shaft through the valve body bore
and bearing. Position the disc as stated above and slide the shaft through the disc and outer bearing. Refer to step 4
below.
D For CL150 metal bearing, three piece assemblies: Slide the shaft into the valve body bore and bearing spacer.
Position the disc spacer as stated above and hold it in place. Slide the shaft through the bearing and into the disc.
Position the second disc spacer, and hold it in place. Slide the shaft through the disc spacer and into the outer
bearing.
