The following general safety information should be taken into account in addition to the specific warnings
and cautions specified in this manual. They are recommended precautions that must be understood and
applied during operation and maintenance of the equipment covered in this I.O.M.
To avoid injury, never attempt disassembly while there are pressures either
upstream or downstream. Even when replacing gaskets, caution is necessary to
avoid possible injury. Disassemble with caution in case all pressures are not relieved.
To prevent valve bending, damage, 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.
This manual provides instructions for storing, general servicing, installation and removal of check valves.
APV and it’s resellers refuse any liability for damage to people, property or plant as well as loss of
