 INTRODUCTION
The design features of this valve include three piece construction
and a “free floating” ball allowing ease of maintenance without
special tools 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 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

 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 Ensure the adjoining
pipe on each end of the valve is aligned to prevent external
piping loads Piping misalignment may cause excessive external
loads on the valve resulting in body joint leaks
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 full or half open position 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
As shipped from the factory valves may 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
 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
ensure 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

Before installing this equipment confirm that it is suitable for the
intended service
The identification tags describe the maximum allowable service
conditions for this product

 Installation of Threaded End Valves
The use of a thread sealant is recommended use conventional
sealant such as hemp core Teflon etc
Apply wrench only on the hexoctagon nearest the valve end
being tightened Do not tighten by applying torque to the
opposite end cap or other valve component Tightening by using
the valve body handle or the opposite end cap can seriously
damage the valve use a wrench on both the near end cap and
pipe to avoid applying torque to the body through the bolting
In some applications threaded end valves may be back-welded
on site Confirm that the end cap bolt holes are aligned with the
body bolt holes on both ends and that the end caps are parallel
and correctly spaced to fit the valve body before re-assembly
or back welding Make up both of the threaded connections
normally and then remove the body assembly as described in
Section  for weld-end connections before back welding the
threaded connection

when the handle is parallel to the axis of the valve and pipe)
loosen all body bolts and remove the body from between the end
caps
Turn the handle to the half open position Remove the seats and
body gaskets
Turn handle to the closed position and remove ball
Place all removed parts in a clean and secure place
Replace the body and all body bolts between the end caps and
tighten them slightly This operation is very important so that the
body and end caps remain perfectly parallel thus preventing any
leakage at the body joint after welding
Finish welding both end caps onto the pipe
When cool remove the body clean end caps and reassemble per
instructions in Section 
NOTICE
Use a spare body gasket for reassembly as the original body
gasket will have been compressed during the original assembly

 DISASSEMBLY PROCEDURE
CAUTION
Line must be depressurized before disassembly Valve should be
cycled after draining the system to relieve any pressure trapped
in valve cavity Ball valves can trap pressurized media when
closed Flush line with valve  open to remove hazardous
media If the valve has been used to control hazardous media it
must be decontaminated before disassembly
WARNING
DO NOT attempt to remove packing components or any other
valve parts while line is under pressure!
CAUTION
Properly support the valve before removing or loosening any
body bolts The larger sizes are heavy and may cause injury if
allowed to swing or fall freely
Remove actuation air and power connections and confirm that
there is no stored energy in the actuation such as compressed
springs or trapped air before beginning Stored energy devices
can cause serious injury if the energy is released without warning
 Disassembly for Stem and Seal Service
It is not necessary to remove the flanges from the pipeline
Removing any actuation and controls may make service easier
For valves sizes up to and including  you may remove one of
the upper body bolts and loosen the remaining bolts The center
body will swing out for service leaving the end caps in place on
the pipe ends It is not recommended to perform in-line service
for valves ” and larger by swinging the center section out due to
the size and weight of the body center section
To completely remove the valve from the pipeline remove the
remaining upper body bolt and the body will lift free Gently
support the body in a vise to complete the remainder of the
disassembly To avoid damage to the seal surfaces hold the body
horizontally across its diameter not across the end faces
Remove the seats body seals and seat supports (if applicable)

To remove the ball rotate the stem so the ball is fully closed
Lift the ball from body using a strap and lift device if necessary
NOTE Extreme caution should be taken to avoid damage to the
ball
The stem must be removed from inside the body - a tap on the
top of the stem should loosen it The thrust washer thrust washer
protector and stem bearing (if applicable) should come out with
removal of the stem Then remove the stem packing set and
packing protector from the packing box A screw driver or pick
may be required to remove the packing rings Use caution not to
scratch the inner diameter of the packing box as this may aect
the ability to properly seal
NOTE Disassembly for servicing seats and stem seals may be
performed without removing the end flanges from the pipeline
This feature allows the removal of the valve from service without
disturbing piping connections

 VISUAL INSPECTION
Clean and inspect metal parts It is not necessary to replace the
ball and stem unless the sealing surfaces have been damaged
by abrasion or corrosion Replacement of all soft parts is
strongly recommended whenever the valve is disassembled for
reconditioning to protect against subsequent leakage after valve
reassembly The soft good 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 assembly and reduce initial operating
torque Lubricant used must be compatible with the intended line
fluid

Install the Belleville washers tab lock washer and stem gland nut
onto the stem Tighten hand tight
Note The Belleville washers are to be installed in an alternating
orientation with the concave side of the washers facing each
other
Turn the stem until the upper stem flat is perpendicular to the
valve centerline (closed so that the ball can fit onto the stem)
Install the ball inside the valve body The lower stem flats will fit

less than the internal diameter of the end cap and ball inserted
through the end cap and ball will prevent the ball from turning as

Secure the handle with the handle nut
Cycle the valve slowly several times By cycling slowly the seats
will align with and conform to the ball A fast turning motion
initially may damage the seats before they have a chance to form
