CAUTION
Do not remove the existing valve stem from the valve plug unless you are planning to replace the valve stem.
Never reuse an old valve stem with a new plug or reinstall a valve stem after it has been removed. Replacing a valve stem
requires drilling a new pin hole in the stem. This drilling weakens the stem and may cause failure in service. However, a
used valve plug may be reused with a new valve stem.
11. Remove the existing valve stem and plug, cage, and seat ring from the valve body following the appropriate
instructions in the Trim Removal section of this manual.
12. Replace all gaskets according to appropriate instructions in the Trim Replacement section of this manual.
13. Install the new seat ring, cage, valve plug/retainer assembly, and stem into the valve body and completely
reassemble the valve package following the appropriate instructions in the Trim Replacement section of this
manual.
