What do you need today? TM
GENERAL
SVF Ball valves have been designed and
engineered to provide long lasting and trouble
free service when used in accordance with the
instructions and specifications herein.
The following instructions refer only to SVF Series
FB9 Ball Valves.
Keep protective cover in place until moment of
installation. Valve performance depends upon
preventing of damage to ball surface. Upon
removal of cover, make sure that the valve is
completely open and free of obstruction.
If requested, valves can be shipped from the
factory containing a silicon based lubricant
which aids in the assembly of the valve. This may
be removed with a solvent if found intolerable.
Certain ferrous valves are phosphate and oil
dipped during the course of manufacture, but
they are completely non-toxic and the valves are
quite safe to use for edible or potable products.
STORAGE:
All manual valves are shipped in the fully open
position with protective end caps (covers). Keep
all protective packaging, flange covers, or end
caps attached to the valves during storage.
To avoid damage to the seat due to contact
with the balls edge, leave the valve in the fully
open or closed positionduring storage. It is
recommended to keep the valves in a clean and
dry environment until ready for use.
!!!CAUTION! Safety Precautions!!!
Before removing valve from pipeline
NOTE that:
Media owing through a valve may be
corrosive, toxic, flammable, a contaminant
or harmful nature. Where there is evidence of
harmful fluids having flowed through the valve,
the utmost care must be taken. It is suggested
that the following minimal safety precautions
be taken when handling valves.
1. Always wear eye shields.
2. Always wear gloves and overalls.
3. Wear protective footwear.
4. Wear protective headgear.
5.Ensurethatrunningwaterisreadilyaccessible.
6. Have a suitable fire extinguisher ready if
media is flammable.
7. Be sure that you are aware of the fluid that
has been passing through the valve before
opening or dismantling any valve. Require
MSDS information.
By checking line gauges ensure that no
pressure is present at the valve.
Ensure that any media is released by operating
valve slowly to half open position. Ideally, the
valve should be decontaminated when the
ball is in the half open position.
These valves, when installed, have body
connectors which form an integral part of the
pipeline and the valve cannot be removed
from the pipeline without being dismantled.
Valves and accessories must not be used as a
sole support of piping or human weight. Safety
accessories such as safety relief (overpressure)
valves are the responsibility of the system
designer.
It is the user/system designer’s responsibility to
use insulation in high temperatureapplications.
Refer to OSHA documents for more details.

IOM - Series FB9 Ball Valves
INSTALLATION
The valve may be installed for flow or vacuum in
either direction. Carefully exclude pipe sealants
from the valve cavity. When installing, use standard
gaskets suitable for the specific service. Tighten
flange bolts or studs evenly.
OPERATION
normal conditions and in accordance with SVF’s
published pressure/temperature chart. If these
valves are used in a partially open (throttled)
position seat life may be reduced.
SVF valves have ¼ turn operation, closing in a
clockwise direction. It is possible to see when
the valve is open or closed by the position of the
wrench handle. When the wrench is inline with the
pipeline, the valve is open.
Any media which might solidify, crystallize or
polymerize should not be allowed to stand in the
ball valve cavities unless regular maintenance is
provided. If minimal maintenance is required, SVF
TORQUE REQUIREMENTS
Torque ratings are subject to variations depending
on the length of time between cycles and the
media in the system.
Breakaway torque is that force which must be
exerted to cause the ball to begin to open.
Operating torque requirements willvary depending
on the length of time between cycles, media in
the system, line pressure and type of valve seat.
MAINTENANCE
With self-wiping ball/seats, SVF valves have a
long, trouble free life, and maintenance is seldom
required.
SVF valves are designed for easy service and
assembly in the field. The following checks will help
to extend valve life, or reduce plant problems.
SVF ball valves utilize live-loaded stem seals
featuring Belleville Washers (disk springs) that
maintain constant pressure on the Stem Seal
area even under a wide range of pressure and
temperature fluctuations. If stem leakage is evident
proceed as follows:
STEM LEAKAGE
Examine the disk springs (Belleville washers) for
damage. If in good condition tighten the stem
nut until disk springs are rmly compressed,
th of a turn. If damaged,
dismantle the stem down to the stem nut, fit
new disk springs with their outer edges touching,
replace and retighten using the stem nut. Further
maintenance necessitates dismantling of the
valve.
LEAKAGE AT BODY JOINT
Check for tightness at the body connector bolts.
If loose, tighten body bolts. Excessive force will
damage the bolts. (See Table A below)
If there is still leakage it will be necessary to
dismantle the valve and replace the body seals.
IN-LINE LEAKAGE
Check that the valve is fully closed. If leakage
occurs while the valve is in the closed position,
a seat or ball sealant surface may be damaged
and it will be necessary to disassemble the valve.
NOTE: If stem leakage and leakage at the body
joint are not cured by simple means described
above, it will be necessary to dismantle the
valve. If there is no stem leakage the stem
assembly should not be touched.
WELDING OF SERIES FB9 VALVES:
1. Place valve in the OPEN position.
2. Align the valve between the pipe ends and
make the appropriate welds according to
standard welding procedures. NOTE: The body
temperature in the seal area must not exceed
392 OF.
3. Allow the valve to cool.
4. Tighten the body bolts according to the torque
values (Page 4, Table A).

REBUILDING
Before rebuilding, check that all the correct
components are available and that they are fit for
reassembly. When rebuilding, cleanliness is essential
maintenance. CAUTION: NO BODY OR STEM
SEALS ARE REUSABLE. Care must be taken to avoid
scratching the seats and seals during installation.
NOTE:Caution must be taken with valves that
have been in hazardous media. They must be
decontaminated before disassembly by relieving the
line pressure and flushing the line with the valve in
the partially open position. Protective clothing, face
shields, gloves, etc., MUST BE USED for this operation.
A DISASSEMBLYOFVALVE (Removed fromline)
1.) Remove the End Connectors (#2) by
removing the Body Bolts (#21).
2.) Once the End Connectors (#2) have been
separated from the Body (#1), remove the
Body Seals (#5 and #5A) and Seats (#4).
3.) Make sure the Ball (#3) is in the closed
position so that it can be removed
from the Body (#1).
B
REMOVING STEM ASSEMBLY
1.) Remove Handle (#16) by removing Handle
Nut (#17).
2.) Remove the Handle Washer (#15), Lock
Tab (#14), Jam Nut (#13), Belleville Washers
(#12), Gland Follower (#11), and Stem
Seals (#10).
3.) Push theStem(#6) downinto the bodycavity
to remove. Once removed take o the
O-ring (#7) and Thrust Washer (#8 and #9).
C INSPECTION
1.) The ball and the surfaces of the seats

2.) The stem and body surfaces, which the
thrust and washer make contact with,
shouldbefree ofpit marks and scratches.
D REASSEMBLY
1.) Apply a small a of lubricant compatible
with the media being handled to the
Seats (#4). Seats may be installed dry, if
required.
2.) For stem reassembly, disassembly
procedure should be followed in reverse
order.
3.) When stem assembly is complete,
tighten Jam Nut (#13 according to the
values in Table A.
4.) With the Stem (#6) in the closed position,
insert the Ball (#3) into Body (#1) so that
stem
slot engages with thetang at the base
of the stem.
5.) Make sure the body seal grove is clean
and free of any debris. Place the Body
Seals (#5 and #5A) on the seal grove of
the Body (#1).
6.) Insert Seats (#4) into the Body (#1). Make
sure seats rest firmly on back surface of
each recess.
7.) Merge the End Connectors (#2) with the
Body (#1).
8.) Insert and tighten the Body Bolts (#21)
diagonally, in accordance to the cross
pattern procedure shown on page 5.
9.) In the final assembly step, ensure that the
Body Bolts (#21) are tightened according
to torque values in Table A.

TORQUE SPECS
Certainprecautionsneedtobefollowedwhen
tightening bolts down to their corresponding
torques to help prevent bolt galling. There
are two passes each bolt has to undergo
during the process, first pass and the final
pass. Once every bolt has met the first pass
requirement, the final pass can be initiated.
When tightening down bolts, it is necessary to
follow the corresponding bolt pattern shown
below.
