SAFETY PRECAUTIONS
• When the safety valve is under pressure never
place any part of your body near the outlet of
the valve.
• Always wear proper safety gear to protect
hands, head, eyes, ears, etc. anytime you are
near pressurized valves.
• Never attempt to remove the safety valve from
a system that is pressurized.
• Never make adjustments to or perform
maintenance on the safety valve while in
service unless the valve is isolated from
the system pressure. If not properly isolated
from the system pressure, the safety valve may
inadvertently open resulting in serious injury.
• Remove the safety valve prior to performing any
pressure testing of the system.
• The safety of lives and property often depends
on the proper operation of the safety valve.
The valve must be maintained according
to appropriate instructions and must be
periodically tested and reconditioned to ensure
correct function.
• For further information including adjustment,
maintenance, cleaning lapping and detail
illustrations obtain the appropriate Operation and
Maintenance Manual from the table at Section 6.
