MATERIAL COMPATIBILITY
Valve structural materials and lubricants should be chemically compatible with other piping system
components, line fluids, and the environment. If compatibility is a concern, guidance should be sought
from appropriate sources (system engineers for example).

The following general safety notices supplement the specific warnings and cautions appearing elsewhere
in this manual. They are recommended precautions that must be understood and applied during operation
and maintenance of the equipment covered herein.
This manual provides instructions for storing, general servicing, installation and removal of plug valves.
APV refuses any liability for damage to people, property or plant as well as loss of production and loss of
income under any circumstances but especially if caused by: Incorrect installation or utilisation of the
valve or if the valve installed is not fit for intended purpose. It is the sole responsibility of the client to
ensure the valve type and materials are correctly specified.
Do not attempt to disassemble a valve while there is pressure in the line. Make sure
both upstream and downstream pressures are removed. Disassemble with caution in
case all pressures are not relieved. Even when replacing packing rings, caution is
necessary to avoid possible injury.
To prevent valve distortion, inefficient operation, or early maintenance problems,
support piping on each side of the valve. Warning, certain gases and fluids could
cause damage to human health, the environment or property, hence the necessary
safety precautions to prevent risk should be taken.
• A valve is a pressurised device containing energised fluids and should be handled
with appropriate care.
• Valve surface temperature may be dangerously too hot or too cold for skin contact.
• Upon disassembly, attention should be paid to the possibility of releasing
dangerous and or ignitable accumulated fluids.
• Adequate ventilation should be available for service
