To help prevent injury to personnel or damage to
equipment, please read this section completely before
performing any operations.
1. Valve pressure ratings are based on many
variables, including valve series and size, as well
as body, seat and bolt material. Verify that
application does not exceed the pressure or
temperature rating on the nameplate.
2. Always depressurize the line with the valve in
the open position before disassembly. Cycle
valve in depressurized line before removing
valve.
3. Wear protective equipment and take appropriate
precautions to safeguard against injury caused by
the discharge of trapped fluids.
Use only Steriflow recommended spare parts for
maintenance.
To ensure safety and maintain warranty, never modify
valve in any way without prior approval from
Steriflow.
No internal lubricant is used on these valves. An FDA
H-1 food grade incidental contact lubricant may be
used on the threads of the body-end cap bolts. All
valves are adequately packed in a strong cardboard
case in such a way as to avoid any possible damage
during transport and storage.
Caution: If ball valves are not destined for
immediate use, the following precautions should
be taken:
1. If possible, leave the ball valves in their
packing cases during the period of storage.
2. Ball valves must remain in open position during this time.
