INSTALLATION - MAINTENANCE MANUAL
F15 and F30 Series
150 and 300 Lb. Flanged Full Port Ball Valves
DESIGN
The design features of this valve include a split body, two
piece construction, allowing ease of maintenance without
special tools. These valves feature a “free floating” ball. The
ball is not fixed, but is free to move with the line pressure.
As a result of this feature, these valves are capable of
tight shut-off with flow in either direction or dead-ended,
regardless of the position of the valve in the line.
The downstream seat, opposite the pressurized side of a
closedvalve,mustcarrytheloadexerted bythelinepressure
on the ball, while the upstream seat is subject to little load
or wear. For this reason, it is sometimes possible to increase
usefulseatlifebyturningthevalveend-for-endin thepipeline.
1. USE
The valve should be maintained as part of a preventative
maintenance program and in accordance with Flow-Tek’s
recommended pressure, temperature and corrosion limits
to insure a long service life. During shipment, storage, and
in operation, the valve should be fully open or fully closed
(“open” is preferred for shipping and storage). Do not use
in throttling service without investigating flow and pressure
conditions.
WARNING: Beforeinstallingthis equipment, confirm
that it is suitable for the intended service.
The identifications tags describe the maximum allowable
service conditions for this product.
Be sure that the installation is protected by appropriate
pressure control and safety devices to insure that acceptable
limits are not exceeded.
2. OPERATION
Operation of the valve is done by turning the handle a 1/4
turn (90 degree turn). CW to close, CCW to open.
A. VALVE OPEN POSITION
The handle is parallel with the pipeline.
B. VALVE IN CLOSED POSITION
The handle is perpendicular to the pipeline.
Valves with actuators should be checked for actuator -valve
alignment.Misalignment willresultin high operationaltorque
and damage to valve stem and seals.
3. STEM SEAL ADJUSTMENT
1. For 1/2”- 2”, if slight leakage is noted at stem,
straighten lock washer tab, tighten stem nut to flatten
BellevilleWashers,backstemnut off1/4turn,secure
lock washer tab.
2. For sizes larger than 2”, simply tighten gland bolts
evenly until leak stops. Do not over tighten.
4. BALL SUPPORT PACKING ADJUSTMENT
Ball Support packing adjustment may be required in the
rare event that the pin packing develops a leak. The below
instructionsshouldbe followedintheeventofaleaktoadjust
the packing. Note that the position of the ball support comes
pre-set from the factory. Adjustment of the pin seat position
may only be required if the ball support components have
been replaced.
1. Loosen the set nut (35) on the tuning screw (36)
by turning the nut counter-clockwise while holding
the screw stationary with an open end wrench.
2. With the set nut (35) loose, turn the support nut
(34) clockwise to compress pin packing (32) as
necessary to stop leakage of line media around
support nut threads.
3. Using finger pressure only, rotate the tuning screw
(36) in the clockwise direction until resistance is
felt from the support pin seat (31) contacting the
ball surface. Then, rotate the tuning screw (36) ¼
turn in the counter-clockwise direction.

5. GENERAL INFORMATION FOR ON-SITE
INSTALLATION
The valve may be installed in any orientation on the pipeline
and should be installed in the full open position
Before installing the valves, the pipes must be flushed clean
of dirt, burrs, and welding residues, or the seats and ball
surface will be damaged. If for any reason the valve is
installed prior to flushing of the piping system, the valve
must remain in the full open position until the piping system
has been fully flushed clean of debris.
6. DISASSEMBLY AND CLEANING PROCEDURE
CAUTION: Line must be depressurized before
disassembly. Valve should be cycled to assure there
is no pressure is trapped in valve cavity. Ball valves
can trap pressurized media when closed. Flush line
with valve 1/2 open to remove hazardous media.
WARNING: DO NOT remove packing gland or any
other valve parts while line is under pressure!
Stem seal leakage may be corrected without disassembly
by tightening the packing gland nut until such leakage
stops. If the leakage continues or valve operating torque
becomes excessive, the seals are worn and replacement
will be necessary.
If the valve has been used to control hazardous media, it
must be decontaminated before disassembly.
It is recommended that the following steps be taken for safe
removal and assembly.
As shipped from the factory, valves contain silicone based
lubricant. This is for break-in and may be removed by
disassembly and solvent washing, if it is objectionable for
a particular application.
7. DISASSEMBLY FOR STEM AND SEAL REMOVAL
1. Remove flange bolts and nuts and lift valve from line
for servicing.
NOTE:Careshouldbetakentoavoidscratching
or damaging serrated flange face. These valves
are heavy!

2. Loosen handle set screw and remove handle and
stop plate. Next, remove gland nuts, gland flange
and gland.
3. Remove body end nuts, using proper wrench size.
Lift off body end. One seat should come out with
body end.
4. Remove body seal.
5. To takeouttheball, rotatestem so ballisinfullyclosed
position. Lift ball from body, using a strap and lift
device, if necessary. NOTE: Extreme caution should
be taken to avoid damage to the ball.
6. Take out other seat.
7. Stem must be removed from inside the body - a tap
on the top of the stem should loosen it. The thrust
washer should come out with the stem. Then remove
the stem packing.
8. VISUAL INSPECTION
Clean and inspect metal parts. It is not necessary to
replace the hall and stem unless the seating surfaces have
been damaged by abrasion or corrosion. We strongly
recommend replacement of all soft parts whenever the valve
is disassembled for reconditioning.
This is the surest protection against subsequent leakage after
valve assembly. The replacement parts can be ordered in
kit form.
NOTE: The valve may be assembled and operated
dry where no lubricants are allowed in the system;
however, a light lubrication of mating parts will aid in
assemblyandreduceinitial operatingtorque.Lubricantused
must be compatible with the intended line fluid.

9. ASSEMBLY
1. Install one seat in the body seat cavity with the
spherical curvature facing the ball.
2. Install thrust washer on stem and slide the stem up
through the body. Install packing and packing gland
with packing gland bolt.
3. Install stop plate, handle and handle retainer nut.
4. Turn the handle CW to the CLOSED position. Line
up the ball slot with the stem tang and slide the ball
into position. For V-control valves, insert V-ball with
V opening facing assembled seat in point 1. V cut in
the ball should be on downstream side (body) seat
following flow arrow marked on the body. Turn the
handle CCW to the OPEN position to hold the ball
in place.
5. Install the remaining seat into end cap seat pocket.
6. Put body seal gasket into shoulder counter bore at
flange in valve body.
7. Put end cap back into body and line up end flange.
Becausethebody flange bolt patternisdifferentfrom
the line flange bolt pattern, it is possible to assemble
the valve which the bolt holes in the line flanges don’t
line up. Be certain to align end flanges bolt holes to
straddle valve center lines.
NOTE: Be careful not to damage body seal
when assembling end into body.
8. Installbodyendnutsandtighteninacrossingpattern
to the torque specified in Table 1.
9. WARNING: Extreme care must be exercised
during adjustment of body stud nuts to make
sure that body studs are fully engaged. There
should be at least one stud thread exposed
beyond the flange on the body side and
beyond the nut on the cap side.
10. Cycle the valve slowly, with a gentle back and forth
motion, to build gradually to the full quarter turn. By
cycling slowly, the seat lips will assume a permanent
seal shape against the ball. A fast turning motion,
at this point, may cut the seats before they have a
chance to form the proper seal.
11 . Test valve, if possible, prior to placing valve hack
into line position. WARNING: If not properly
secured, the valve can separate from the
pressure source, resulting in possible injury.
Always join the valve to companion.
12. Flanges of same pressure rating as valve and secure
with a full set of flange bolts.

TEST AS FOLLOWS
1. Secure valve to a test future by means of a mating flange
with full bolting and a suitable gasket. Orient valve so
seat to he tested is facing up.
2. Introduce 50 to 100 psig air. Partially cycle the valve,
under pressure, and then slowly close to make sure the
cavity is pressurized (use hearing protection). Pour
water into the upper port to cover the ball and visually
check for bubbles. If bubbles appear, pour the water
out, cycle the valve several times and recheck. To check
for leakage in the other port, reverse the valve and
introduce air pressure to the port just checked.
3. Check stem seal at this time by coating the gland area
with a soapy water solution. If leakage occurs, tighten
stem seal just until leakage stops.

periods of one to three months. Short-term storage must be
carried out in a controlled manner as follows:
1. Valves must be stored in a closed, clean, and dry
environment.
2. Ball valves should be stored in the fully open
position to protect the ball and seats.
3. Ball valves should remain in the original shipping
container and be placed on pallets of wood or
other suitable materials. End protectors should
remain on the valve ends to prevent the entrance of
dirt, and removed only at time of installation.
LONGTERM STORAGE
Long-term storage is defined as storage of products and/
or equipment for periods longer than 3 months. Long-term
storage must be carried out in a controlled manner as
follows:
1. Valves must be stored in a closed, clean, and dry
environment.
2. Ball valves should be stored in the fully open
position to protect the ball and seats.
3. Ball valves should remain in the original shipping
container and be placed on pallets of wood or
other suitable materials. End protectors should
remain on the valve ends to prevent the entrance of
dirt, and removed only at time of installation.
4. Periodically, the valves should be checked to ensure
the above conditions are maintained.
These are general guidelines for valve storage. Please
consult the factory for information regarding specific
