Put Into Service; Dangers Of Inappropriate Use; Maintenance - Modentic GLOBE Series User Manual

provides the fasteners information.
To tight the bolts of the flange end caps, the
force must distribute on the every single bolt
evenly. The order to tight the bolts need to be
symmetrically.
5.4 Hanger Inspection
Proper installation and maintenance of the pipe
hangers are essential for the proper functioning
of the valve installed. The valve and adjoining
pipes should always be kept in a straight line.

6. Put into service

a. Once pipe installation is completed, open all
valves completely and flush the piping with
air, water or steam.
b. After flushing, close the valves completely
and Globe that they function properly, if the
valves do not close, disassembly and
inspection should be performed.
c. Systems hydrostatic test
Before delivery, valves are tested 1.5 times
the allowable working pressure at ambient
temperature in
installation, the pipe line system may
subject to system tests, as condition not to
exceed the maximum working pressure.
d. After pressure testing, user shall operate the
valve again about 3 times to ensure the
function.

7. Dangers of inappropriate use

a. Never uses the product exceed its allowed
condition, such as pressure, temperature and
fluid.
b. If the product has any inappropriate use, the
product was damage however there are no
signals occurs
change the product to avoid danger in the
future.

8. Maintenance

a. Maintenance frequency
The maintenance frequency is determined
upon the application. User shall consider the
open position. After
immediately. User shall
time interval depend on the kinds of fluid,
flow velocity,
high-pressure effect and high-temperature
effect etc.
b. Emergency repair
When leakage occurs at the pipe connection
flange, tight the bolts of the flange end caps,
the force must distribute on the every single
bolt evenly. The order to tight the bolts need
to be symmetrically. For long-term purpose, it
is need to be re-installed with new seal.
c. Disassembly
(NOTE If complete
replacement of all seats and seals is recommended.)
(1) To dismantle the valve must follow the
procedure below.
(2) It doesn't matter where the position of
valve located is; usually it contained the
seal up fluid, so operator must be very
carefully when moving the valve on the
pipe. It must open the ball a little and let
the fluid come out slowly, it also need to
watch out the poisonous and inflammability
objects if there is any.
(3) To lift the screenl by hoist, it must make
the protection on corner to avoid the
screendamaged by metal contacted.
