Bardiani valves have been designed exclusively for moving uids.
Prohibited use
The valve must not be used:
• for any operations different to those described under the heading “Intended Use”,
• for handling uids different to the type specied by the manufacturer;
• for moving uids 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 conguration different to the one envisaged by the manufacturer.
• use the valve where there is a risk of explosion and/or re, unless envisaged by the manufacturer (if
the valves are certied in accordance with Directive 2014/34/EU, please refer to the ATEX Manual)-;
• integrate other systems and/or equipment which were not considered by the manufacturer during the

4 Checking / Unpacking / Lifting
EN-IST-BBZM-0123
4 Checking / Unpacking / Lifting
1. CHECK:
-Check the valve show no signs of damage caused during transport
and that it corresponds with the order;
-Check the inside of the valve.
2. UNPACKING
The valve packaging is made up of cardboard, wood and plastic.
The valve is mainly made up of metal materials. The gaskets are
usually made from elastomers. The handle in the DN15 - DN100
sizes is made from plastic (POM-C). Disposal must be in compliance
with local legislation.
3. VALVE LIFTING:
Take care as to the type of valve you are handling.
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.
DN10 and DN150
Weight up to 25 kg
CAUTION!
The gures 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.

1. PNEUMATIC SUPPLY:
-Use expert personnel for installation/uninstallation operations.
A = Valve opening
B = Valve closing
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.
3. CORRECT DIRECTION OF FLOW:
Flow in the opposite direction to valve closure minimizes water
hammer.
CAUTION!
Bardiani Valvole S.p.A. declines all liability for any damage to things
and/or injuries to persons caused by any failure to correctly follow
the installation procedures.

EN-IST-BBZM-0123
9 Disposal
At the end of its service life, the device must be recycled in accordance with the legislation in force in the
country of valve use.
Any hazardous residues must be taken into consideration and adequately handled.
The valve is made of AISI 316L and AISI 304 stainless steel, elastomers (gaskets), plastic (control unit)
and electrical components (terminal boards, solenoid valves, sensors).
Adhere to the following steps before disconnecting the valve and refer to the heading "General
Maintenance".
-make sure the line on which the valve is installed in is not in use
-empty the line on which the valve is installed and clean if necessary
-disconnect the air supply if it is not required during dismantling
-disconnect the valve from the power supply
-remove the valve from the system
-move the valve in observance of the rules set out in the heading "Lifting"
-to dismantle the valve, refer to the heading "Disassembly"
