Caution
Valve pressure ratings are based on many vari- 1.
ables, including valve series and size, as well as
body, seat and bolt material. Verify that applica-
tion does not exceed the pressure or temperature
rating on the nameplate.
Always depressurize the line with the valve in the 2.
OPEN position before disassembly. Cycle valve in
depressurized line before removing valve.
Wear protective equipment and take appropriate 3.
precautions to safeguard against injury caused by
the discharge of trapped fluids.
Use only Marwin recommended spare parts for 4.
maintenance.
To ensure safety and maintain warranty, never 5.
modify valve in any way without prior approval from
Marwin.
Storage
A petroleum-based oil (silicone free) is used as lubrica-
tion on all internal surfaces. This may be removed with a
solvent if found objectionable. All valves are adequately
packed in a strong cardboard case in such a way as to
avoid any possible damage during transport and stor-
age.
Caution: if ball valves are not destined for immediate
use, the following precautions should be taken:
If possible, leave the ball valves in their packing 1.
cases during the period of storage.
Ball valves must remain in open position during this time. 2.
In order to prevent damage, protective plastic 3.
covers on valve ends should not be removed until
immediately prior to installation.
It is advisable to store the valves in waterproof con- 4.
ditions. Ball valves should be protected to safeguard
against humidity, moisture, dust, dirt sand, mud, salt
spray and seawater.
All valves complete with actuators are to be stored 5.
in dry conditions.
Valves to be stored for a long period of time should 6.
be checked by the quality control personnel every
six months; every three months when valves are
automated.
Maintenance During Storage Period

dust or other foreign objects.
Rust or dust must be removed by cleaning with •
proper solvent.
After cleaning, ball valves must be lubricated with •
an adequate lubricant.
Ball valves should be operated for at least two com- •
plete cycles before installing or returning to storage.
