1. General
The instructions and list of spare parts are applicable to
ShearStream SB ball sector valves in accordance with
catalogue sheet FCD NFEETB4152-01.
2. Lifting
All lifting must be carried out on the valve itself and not
on the actuator. The joint between the valve and the actua-
tor is designed for carrying the operating torque and the
weight of the actuator - see Fig. 1.

3. Receiving Inspection
All valves leaving our plant are inspected and tested in
accordance with the relevant requirements or in accor-
dance with the requirements specifi ed by the purchaser.
Valves equipped with actuators are subject to functional
testing and are adjusted in such a manner that every unit
during transport, it is advisable that receiving inspection
We would suggest the following inspection procedure:
- Check that
the valve delivered is correct in
terms of type, size, equipment
- Examine the valve, actuator and valve positioner
regarding possible damages

the pipework is
free from impurities
the valve is to be installed are parallel and are correctly
aligned, and that the distance between the pipe ends
corresponds to the valve length, including gaskets.
The
valve could not be used for forcing together or aligning
as this will cause loads on the valve
and pipe which may lead to diffi cult damages during
operation. See Fig. 3.

any faults should immediately be corrected
9.1 To remove the valve from the pipework
The procedure for inspection and maintenance, for
which no special tools are necessary, is as follows:
also the gaskets - important - for the pipe
fl anges are available.
2. Close the valve.
3. Shut off all compressed air connections
and isolate all electrical connections to the
actuator.
4. Disconnect all compressed air lines and electric
cables connected to the actuator.
5. Release the fl anged joint between the valve
and the pipework. Then lift out the valve. Don’t
use the actuator for lifting.
Apply all lifting
forces to the valve itself and not to the actuator
- see fi g. 1.

arrow on the valve body.
9.2 To inspect the ball sector and seat ring
section 9.3, items 1 and 2.
2. Remove the indicating pin (23 - fi g. 4).
3. Turn the ball sector through more than 90°, until
it is no longer in contact with the seat ring.
4. Push the seat ring out of its seat at the valve
body inlet. Withdraw it past the ball sector -
between the ball sector and the inside
of the valve body - towards the outlet, and
remove it from the body.

5. Remove the compression spring (10) in the
same way.
6. Carefully wash all parts with warm water and
then, if necessary, with a suitable solvent. Never
scrape the sealing surfaces with hard tools.
7. Examine the surface of the ball sector (2).
Remove any deposits and clean the ball sector
as described in item 6 above.

8. Inspect the seat ring (11) and clean it as
described in item 6 above.
9. Inspect the sealing ring (12) - it need not be
removed from its groove in the body. Fit a new
sealing ring if the original one is damaged.

with a silicone-base grease, such as Silicone
grease DC 111, Silicone grease TKM 1011 or
similar.
Turn the ball sector (2) until it is in contact with
seat ring (11). Use a soft object to press the
seat ring towards the compression spring (10)
to enable the ball sector to move into its proper
position. Continue turning the sector to the
closed position.
pin is to restrict the travel of the ball segment
to 95 - 100°, so that it will always remain in
contact with the seat ring.
9.3 To inspect and replace the upper shaft seal of
Safeguard type
The stuffi ng box usually requires inspection and adjust-
After a certain period of time in service, it may some-
times also be necessary to replace the packing.
Begin by removing the valve positioner. This
can easily be done after the plastic cover of the
valve positioner has been removed. Remove the
four bolts securing the valve positioner to the
actuator. Then remove the nuts securing the
actuator to the valve mounting plate and dismantle
the actuator.
2. Remove the key.
3. Remove the nuts (18). Remove the gland (5).
Then remove the packing (19).
4. Clean the surfaces of the stem, gland (5) and
packing area in the valve body.
5. Carefully examine the surface of the stem which
must be completely free from marks and
scratches.
6. Grease the stem with a suitable grease, such as
Silicone grease.
7. Mount new packing (19). Then mount the gland
(5) and the nuts (18).
8. Tighten the nuts (18) suffi ciently to ensure that
the packing is correctly seated.

tems 1. Remove the keys (22) and the indicator
pin (23).
2. Remove the nuts (18), spring cups and gland (5).
Then remove the packing (19).
3. Clean the surfaces of the stem, gland (5) and
packing area in the valve body.
4. Carefully examine the surface of the stem which
must be completely free from marks and
scratches.
5. Grease the stem with a suitable grease, such as
Silicone grease.
6. Mount new packing (19) when mounting the
gland (5) and the spring cups and then the
nuts (18).

9.5 To change the gasket at the lower stem
with the inspection of the seat ring (11).
2. Remove the bolts (20) and the cover (6).
3. Withdraw the stem (4) and remove the gasket (7).
4. Carefully clean the inside of the cover (6) and the
stem (4).
5. Fit a new gasket (7) and lubricate the small end
of the stem with a suitable lubricant, such as
Molykote Paste U or Gleitmo 700.
6. Fit the stem (4) with the gasket (7).
7. Spray the bolt threads with locking compound,
such as Loctite 641.
8. Fit the cover (6) and tighten the bolts (20).

10. Fitting the Actuator to the Valve
valve. The mounting fl ange and the valve stem
follow the NAF standard for securing the
actuator.
2. Turn the valve to the closed position. The key
should face towards the inlet.
3. Fit the actuator.
4. Connect the compressed air supply to the
actuator - applies to pneumatic actuators. If the
end position stop is correctly set, the ball
segment will not move when compressed air
pressure is applied.
5. If moving - adjust the end position stop until the
actuator has turned the ball segment to the
closed position.
6.
The actuator may be fi tted either in line with the
connected pipes or transversely to them. An
intermediate plate is necessary for mounting the
actuator in line with the pipework.
the actuator fi ts the stem. First try without key to check
that the drive slips onto the shaft. Also check that the
actuator shaft entry. Push the actuator onto the stem.
The travel of the ball sector should be restricted to 90°
which is the travel necessary between fully open and
fully closed. If the sector is turned beyond this range,
the sealing surfaces of the sector and seat ring may
will come into contact with the bolts retaining the top
cover if an attempt is made to turn the ball sector outside
the range between fully open and fully closed. When
adjusting the actuator, make sure that, in the closed posi-
tion, the sphere of the ball sector (2) is located opposite
the seat ring (11), i.e. that the sphere projects beyond the
seat ring by equal amounts on each side of the seat as
shown in Fig. 5.
