 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-
o 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 closed
valve, must carry the load exerted by the line pressure on the
ball, while the upstream seat is subject to little load or wear. For
this reason, it is sometimes possible to increase useful seat life by
turning the valve end-for-end in the pipeline.
 USE
The valve should be maintained as part of a preventative
maintenance program and in accordance with manufacturer’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
Before installing this 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.

 OPERATION
Operation of the valve is done by turning the handle a 1/4 turn
(90 degree turn). CW to close, CCW to open.
 Valve Open Position
The handle is parallel with the pipeline.
 Valve in closed Position
The handle is perpendicular to the pipeline.
Valves with actuators should be checked for actuator -valve
alignment. Misalignment will result in high operational torque and
damage to valve stem and seals.
 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.
For hydrostatic testing of the piping system, the valves must be
placed in the half open position prior to pressurizing the system.
If the valve is installed in a dead-end position on the piping, the
valve must be placed in the half open position and equipped with
a blind flange prior to pressurizing the system.
NOTICE
Hydrostatic system testing with the valve in the closed position
may result in damage to the valve seats aecting their ability
to create a proper seal Failure to implement the installation and
testing instructions as outlined, resulting in a valve failure, will
void the warranty coverage of the product.

 SHORT AND LONG-TERM STORAGE
 Short-Term Storage
Short-term storage is defined as storage of products and
equipment to be used in the construction of a project for 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 requirements.

 STEM SEAL ADJUSTMENT
For 1/2"- 2", if slight leakage is noted at stem, straighten lock
washer tab, tighten stem nut to flatten Belleville Washers, back
stem nut o 1/4 turn, secure lock washer tab.
For sizes larger than 2", simply tighten gland bolts evenly until
leak stops. Do not over tighten. See Table 1 for recommended
gland nut torque.
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.

 BALL SUPPORT PACKING ADJUSTMENT
Ball Support packing adjustment may be required in the
rare event that the pin packing develops a leak. The below
instructions should be followed in the event of a leak to adjust 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.
4. Lock the tuning screw (36) in position with the set nut (35)by
holding the tuning screw (36) head stationary with an open
end wrench while firmly tightening the set nut (35) in the
clockwise direction.

 DISASSEMBLY AND CLEANING PROCEDURE
CAUTION
Line must be depressurized before disassembly. Valve should be
cycled to assure there is no pressure trapped in valve cavity. Ball
valves can trap pressurized media when closed. Flush line with
valve in the half open position to remove hazardous media.
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.

 DISASSEMBLY FOR STEM AND SEAL REMOVAL
Remove flange bolts and nuts and lift valve from line for
servicing.
NOTE Care should be taken to avoid scratching or damaging
serrated flange face. These valves are heavy!
They should be adequately supported before removal from the
line is begun.
Loosen handle set screw and remove handle and stop plate. Next,
remove gland nuts, gland flange and gland.
Remove body end nuts, using proper wrench size. Lift o body
end. One seat should come out with body end.
Remove body seal.
To take out the ball, rotate stem so ball is in fully closed 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.
Take out other seat.
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.
 VISUAL INSPECTION
Clean and inspect metal parts. It is not necessary to replace the
ball 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
to protect against subsequent leakage after valve reassembly.
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 assembly and reduce initial operating
torque. Lubricant used must be compatible with the intended line
fluid.

 ASSEMBLY
Install one seat in the body seat cavity with the spherical
curvature facing the ball.
Install thrust washer on stem and slide the stem up through the
body. Install packing and packing gland with packing gland bolt.
Torque the packing gland nut with recommended values from
Table 1 (page10).
Install stop plate, handle and handle retainer nut.
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.
Install the remaining seat into end cap seat pocket.
Put body seal gasket into shoulder counter bore at flange in valve
body.
Put end cap back into body and line up end flange. Because the
body flange bolt pattern is dierent from 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
Install body end nuts and tighten in a crossing pattern to the
torque specified in Table 2.

Assembly - Continued
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.
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.
Test valve, if possible, prior to placing valve back into line
position.
WARNING
If not properly secured, the valve can become separated from
the pressure source, resulting in possible injury. Always join the
valve to flanges of the same pressure rating and secure with a full
set of flange bolts.
TEST AS FOLLOWS
1. Apply test flange to the valve with full set of flange bolts
and a suitable gasket. Orient the valve with the bore in the
vertical position and the seat being tested 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.
