ANDERSON GREENWOOD SERIES 9300 PILOT OPERATED SAFETY RELIEF VALVES
INSTALLATION AND MAINTENANCE INSTRUCTIONS
5 STORAGE AND HANDLING
Because cleanliness is essential to
the satisfactory operation and tightness of
a Series 9000 pilot operated relief valve,
precautions should be taken to keep out all
foreign particles and materials. Valves should
be closed off properly at both the valve inlet
and outlet. Particular care should be taken
to keep the valve inlet absolutely clean.
Valves should preferably be stored indoors
with the original factory installed protective
measures left in place. This includes all
desiccants, flange protectors, and factory seals.
FIGURE 16
Valves should be placed on wooden pallets
or other blocking materials to keep them off
the floor or in a location where dirt and other
forms of contamination are kept to a minimum.
Valves should not be thrown in a pile or laid on
the bare ground waiting for installation.
