3.  To replace the adaptor (key 24, figure 14) on
ENVIRO-SEAL bellows seal bonnets, place the plug
stem assembly and valve plug in a soft-jaw chuck or
other type of vise so that the jaws grip a portion of
the valve plug that is not a seating surface. Drive out
the pin (key 36, figure 14). Reverse the plug stem
assembly in the soft-jaw chuck or vise. Grip the flat
areas on the valve stem just below the threads for
the actuator/stem connection. Unscrew the valve
plug/adaptor assembly (key 24, figure 14) from the
valve stem assembly (key 20, figure 14).

4.  Screw the new stem or adaptor into the valve
plug. Tighten to the torque value given in table 5.
Refer to table 5 to select the proper hole size. Drill
through the stem or adaptor, using the hole in the
valve plug as a guide. Remove any chips or burrs
and drive in a new pin to lock the assembly.

5.  For ENVIRO-SEAL bellows seal bonnets, grip the
flats of the stem extending out of the top of the
bellows shroud with a soft-jaw chuck or other type of
vise. Screw the valve plug/adaptor assembly onto
the valve stem. Tighten as necessary to align the pin
hole in the stem with one of the holes in the adaptor.
Secure the adaptor to the stem with a new pin.

Assembly

Except where indicated, key numbers are referenced
in figure 16 for standard 1- through 6-inch
constructions, figure 17 for Whisper Trim III detail,
figures 18 and 19 for WhisperFlo detail, and figure
20 for Cavitrol III detail and the 8-inch Design ET
valve.

1.  With a restricted-trim seat ring construction,
install the adaptor gasket (key 14) and seat ring
adaptor (key 5).

2.  Install the seat ring gasket (key 13), seat ring or
liner (key 9), or disk seat (key 22). With a PTFE-seat
construction, install the disk and disk retainer (keys
21 and 23).

3.  Install the cage or cage/baffle assembly (key 3).
Any rotational orientation of the cage or assembly

with respect to the valve body is acceptable. A
Whisper Trim III cage designated by level A3, B3, or
C3 may be installed with either end up. The level D3
cage/baffle assembly or Cavitrol III cage assembly,
however, must be installed with the hole pattern end
next to the seat ring. If a cage retainer (key 31) is to
be used, place it on top of the cage.

4.  For constructions other than TSO (tight
shutoff) trim, slide the valve plug (key 2) and stem
assembly, or valve plug and ENVIRO-SEAL bellows
seal assembly, into the cage. Make sure the seal
ring (key 28) is evenly engaged in the entrance
chamfer at the top of the cage (key 3) or cage
retainer (key 31) to avoid damaging the ring.

5.  For TSO (tight shutoff) trim constructions,
perform the following steps (refer to figures 6 and 7).

Thread the outer plug onto the inner plug until

the parts seat metal to metal, using a strap wrench
or similar tool that will not damage the outer plug
guide surfaces.

Mark the top of the inner plug and outer plug

with alignment marks in the assembled position.

Disassemble the outer plug from the inner plug

and install the seal over the inner plug, so that the
seal rests below the threaded area.

Thread the outer plug onto the inner plug and

tighten with a strap wrench or similar tool until the
alignment marks line up. This will ensure that the
plug parts are metal to metal and the seal is
compressed properly. Do not damage the outer plug
guide surfaces.

Install set screws centering the inner plug in the

outer plug and torque to 11 N

m (8 lbf

ft).

Assemble the piston ring, anti-extrusion rings,

backup ring, and retainer.

6.  For all constructions, place the gaskets (keys
12, 11 or 14 if used, and 10) and the shim (key 51)
on top of the cage or cage retainer. If there is a cage
adaptor (key 4) or a bonnet spacer (key 32), set it on
