TRANSPORTATION AND STORAGE
Check the valve and the accompanying devices for any dam-
age that may have occurred during transport.
Store the valve carefully. Storage indoors in a dry place is
recommended.
Do not remove the flow port protectors until installing the
valve.
Move the valve to its intended location just before installation.
The valve is usually delivered in the open position.

INSTALLATION
3.1
General
Screwed end valves have NPT threads. To insure a leak tight
joint, liberal use of a compatible pipe joint compound is
necessary. The Eliminator may be installed for flow in either
direction. It is recommended, however, that a screwed valve
be installed with the body cap facing upstream. Use standard
piping practices when installing valves with threaded parts.
When tightening the valve to the pipe, apply the wrench to
the end nearest the pipe being worked (see Figure 3).

Figure 3 Wrench Instructions
It is not recommended to install the valve with the stem on
the underneath side because dirt in the pipeline may then
enter the body cavity and potentially damage the stem
seals (see Figure 4).
Figure 4 Avoid this mounting position
Remove the flow port protectors and check that the valve is
clean inside. Clean valve if necessary.
Flush the pipeline carefully before installing the valve.
Foreign objects, such as sand or pieces of welding elec-
trodes, will damage the ball and seats.
3.2
Installing in the pipeline
Refer to the Section 4, MAINTENANCE for stem seal adjust-
ment. If there is weepage past the stem seals upon installa-
tion, it means the valve may have been subject to wide tem-
perature variations in shipment. Leak- tight performance
will be restored by a simple stem seal adjustment described
in the MAINTENANCE section.
3.3
Valve Insulation
Jamesbury
Thread-end Ball Valves do not require insulation.
If desired, the valve may be insulated; however, the insula-
tion must not continue above the upper level of the valve
(see Figure 5).

Commissioning
Ensure that there is no dirt or foreign objects left inside the
valve or pipeline. Flush the pipeline carefully. Make sure
that the valve is fully open when flushing.
