 INTRODUCTION
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

 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
 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

protect the ball and seats
 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

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

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
 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
 Introduce  to  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
 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
