GENERAL

SVF Ball valves have been designed and engineered to
provide long lasting and trouble free service when used
in accordance with the instructions and specifications
herein.
The following instructions refer only to SVF Series VB41
Control "V" Port Ball Valves.
Keep protective cover in place until moment of
installation. Valve performance depends upon
preventing of damage to ball surface. Upon removal
of cover, make sure that the valve is completely open
and free of obstruction.
If requested, valves can be shipped from the factory
containing a silicon based lubricant which aids in the
assembly of the valve. This may be removed with a
solvent if found intolerable.
Certain ferrous valves are phosphate and oil dipped
during the course of manufacture, but they are
completely non-toxic and the valves are quite safe to
use for edible or potable products.
STORAGE:
All manual valves are shipped in the fully open position
with protective end caps (covers). Keep all protective
packaging, flange covers, or end caps attached to
the valves during storage. To avoid damage to the seat
due to contact with the balls edge, leave the valve in
the fully open or closed position during storage. It is
recommended to keep the valves in a clean and dry
environment until ready for use.

!!!CAUTION! Safety Precautions!!!
Before removing valve from pipeline NOTE that:
Media flowing through a valve may be corrosive,
toxic, flammable, a contaminant or harmful
nature. Where there is evidence of harmful fluids
having flowed through the valve, the utmost care
must be taken. It is suggested that the following
minimal safety precautions be taken when
handling valves.
1. Always wear eye shields.
2. Always wear gloves and overalls.
3. Wear protective footwear.
4. Wear protective headgear.
5. Ensure that running water is readily accessible.
6. Have a suitable fire extinguisher ready if media
is flammable.
7. Be sure that you are aware of the fluid that has
been passing through the valve before opening or
dismantling any valve. Require MSDS information.
By checking line gauges ensure that no pressure
is present at the valve.
Ensure that any media is released by operating
valve slowly to half open position. Ideally, the valve
should be decontaminated when the ball is in the
half open position.
These valves, when installed, have body connectors
which form an integral part of the pipeline and
the valve cannot be removed from the pipeline
without being dismantled.
Valves and accessories must not be used as a
sole support of piping or human weight. Safety
accessories such as safety relief (overpressure)
valves are the responsibility of the system designer.
It is the user/system designer's responsibility to use
insulation in high temperature applications. Refer
to OSHA documents for more details.
