Installation of Metal, Bi-directional Metal or
Heavy-Duty Composition (TCM) Ball Seal
Continued,
3. Check for nicks and scratches on the ball seal,
sealing surface, and backup ring. Install the
ball seal and the backup ring on top of
the shim seals. If damage was
detected on any of the components, the
damage should be turned away from
the V-ball. Install the bi-directional ball
seals, to ensure proper orientation, use
the marks made in step number
5 of the removal.
4. Metal and TCM ball seals:
4.1 Install seal protector ring (key 22) on the
ball seal and shim seals (key 23 and key
20).
4.2 Secure the seal protector ring and the
ball seal to the valve body by threading
and tightening the capscrews. To obtain
the closest ball deflection to zero, add
and remove shim seals (key 20).
4.3 Zero ball seal deflection is when a .005
inch or 0.13 mm shim causes the seal to
be broken between the v-notched ball
and the ball seal. The parts must be
secure or an inaccurate zero will result.
5. Bi directional metal ball seals:
5.1 Install seal protector ring (key 22) on the
ball seal and shim seals (key 24 and key
20).
5.2 Secure the seal protector ring, ball seal
and shims (key 24 and 20) by threading
and tightening the capscrews (key 19).
5.3 Zero ball seal deflection can be tested
by removing the 1/1000 of an inch or
.025 mm thick test shim from under the
ball seal. If this is possible, remove the
seal protector ring, the ball seal, and the
back-up ring.
5.4 To check the zero deflection, remove
one shim, and assemble the
parts. Attempt to remove one 1/1000
inch or 0.025mm shim. If the shim is
neither too tight or too loose,
then zero deflection is obtained.
6. Once zero deflection is obtained remove:
6.1 The seal protector ring
6.2 The ball seal
6.3 The back up ring (if the bi-directional
metal seal is used)
6.4 The number of seals indicated in table
4.
6.5 For the bi-directional metal ball seal
leave at least one shim seal in the
body.
7. Install the ball seal and the backup ring, if one
is used.
8. For metal ball seals, install one shim seal (key
20) on top of the metal ball seal.
9. Install 0-ring (key 24), if used, into the body.
10. Ensure that the ball seal is centered on the V-
ball. For the bi-directional ball match orienta-
tion marks that were made in step 5 of the
removal section.
11. Install the seal protector ring (key 22) and
screw the cap screws and washers, (if used) to
secure the body.
Installation of Flow Ring
1. Ensure that the V-ball (Key 21) is in the closed
position. Replace the shim seals in the body
Table #3
2. Install the O-ring (Key 24) in the body and posi-
tion the flow ring to ensure that it is centered
and that it does not touch the v-ball.
3. Install the washers that hold the seal protector
and twist on the cap screws.
4. Check the minimum clearance of the flow ring
and the V-ball from table 5. Measure the exist
ing clearance and adjust to obtain the minimum
clearance by adding and removing shims.
