5. Rotate the disc (key 3) to the fully open position.
6. Locate the small ends of the taper pins. Drive the two taper pins (key 10) out towards the larger end of the pins.
(Note: Attempting to drive the taper pins in the opposite direction only tightens the pins.) Also, remove the hollow
pins (key 9) from the disc/shaft connection using the tool shown in figure 13.
Note
Make the tools for removal and installation of the hollow pin shown in figure 13.
7. Unscrew and remove the packing flange nuts (key 101), and the packing flange (key 102).
WARNING
Once the shaft has been removed in the following step, the disc may fall out of the valve body cavity. To avoid personal
injury and property damage, support the disc to prevent it from falling as the shaft is being removed.
8. Pull the shaft out of the valve body, and remove the disc (key 3) from the valve body bore.
9. If the packing is to be replaced, remove all the packing parts from the valve body. Upon re‐assembly of the valve,
refer to the Packing Maintenance procedures to replace the packing parts.
10. Remove both of the bearings (key 6) from the valve body. For CL150 valves with metal bearings, refer to the
following note.
Note
CL150 valves with metal bearing assemblies have three parts. A disc spacer, bearing, and bearing spacer (keys 7, 6, and 13) are
used in place of a single piece bearing. The disc spacers may fall out of the valve when the disc is removed. If needed for
re‐assembly, retain disc spacer and bearing spacer parts.
11. Clean all the sealing surfaces and parts, and inspect and/or obtain replacements before assembly.
Assembly
1. Install the bearings (key 6):
When installing the bearings in the opposite side of the valve body bore, repeat the following procedures.
D For PEEK/PTFE CL150 and CL300 metal bearings, one piece bearings: Position the bearing edge to match the valve
body bore, and insert the one piece bearing/disc spacer into the bearing bore with the bearing tab facing away from
the disc stop as shown in figure 12.
D For CL150 metal bearings, three piece assemblies: Bearings for CL150 valves are an assembly made up of three
parts: disc spacer, bearing, and bearing spacer (keys 7, 6, and 13) as shown in the metal bearing detail shown in
figure 14.
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.
