• for handling fluids different to the type specified by the manufacturer;
• for moving fluids at different pressures to those envisaged by the manufacturer and indicated in the
valve's technical data.
Limitations on valve use
It is forbidden to:
• use the valve in a construction configuration different to the one envisaged by the manufacturer.

3. VALVE LIFTING:
Take care as to the type of valve you are handling. Based on the size
there are two different lifting procedures.
CAUTION!
Before lifting the valve, make sure there are no disassembled or
separate valve parts which could fall off causing injury to persons
and damage to the valve.
CAUTION!
The figures above are used purely to represent the methods and procedures for hoisting the valves.
Bardiani Valvole S.p.A. declines all liability for any damage to things and/or injuries to persons caused
by improper and/or incorrect hoisting of the valve.

5 Installation
1. ELECTRICAL AND PNEUMATIC ENERGY SUPPLY
-Use expert personnel for installation/uninstallation operations;
-Check that the air pressure and quality are correct (see "Technical
Data");
-Check the power supply to the control unit is correct (consult the
relative instruction manual).
A = Upward movement of the valve member
B = Downward movement of the valve member
In single acting valves there is only one of the aforementioned
commands.
2. REDUCING THE STRESS TO WHICH THE VALVE IS SUBJECTED:
-Vibrations;
-Thermal expansion of the piping;
-Excessive welding;
-Overload.
CAUTION!
The seal seats may become deformed or cause valve malfunctioning.
