Ball Seal or Flow Ring Maintenance
Caution must be used when working near the
V-ball. The V-Ball closes with a shearing, cutting mo-
tion and can cause personal injury or property dam-
age if objects become caught in a closing valve. Be
sure to keep the path of the V-notch valve clear while
stroking the valve.
Disassembly:
1. Isolate the valve from the line.
1.1 It is necessary for the removed valve to
be positioned so that the seal
ring or flow ring is pointed upward
1.2 Ensure that V-ball (key 21) is in the open
position.
2. Remove the cap screws that secure the seal
protector ring in place.
3. Carefully remove the ring from the body,
ensuring that the surface of the ball is not nicked
or scraped.
4. Remove the O-ring (key 24), if used.
5. Mark the position of the ball seal and the valve
body, so that it can be returned to its
original position when it is reinstalled.
6. Carefully remove:
6.1 The bi-directional metal or TCM ball seal
(key 23)
6.2 The back-up ring
6.3 Shim seals
7. Clean all parts and inspect for damage.
Installation of Metal, Bi-directional Metal or
Heavy-Duty Composition (TCM) Ball Seal
1. Inspect the sealing surface of the valve body
for nicks and scratches that will prevent
the shims from sealing.
2. Turn the V-ball to the closed position and
install the appropriate number of shims
(Key 20) from table 3. For the bi-directional
metal ball seal, use a 1/1000-inch or 1/4 mm
thick test shim. A piece of paper would
be a suitable alternative.
Place the test shim across the ball face.
