2 General safety warnings
Intended use
Bardiani valves have been designed exclusively for moving fluids.
Prohibited use
The valve must not be used:
• for any operations different to those described under the heading “Intended Use”,
• 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.
• use the valve where there is a risk of explosion and/or fire, unless envisaged by the manufacturer (if
the valves are certified 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

concerning internal manufacturing checks as indicated in the Conformity Assessment Procedures.
The DN15--25 valves are included in compliance with Article 4, paragraph 3:
Valves designed for use with gas, liquid gas, gases dissolved under pressure, steam and those liquids
with a vapour pressure at maximum admissible temperature exceeding 0.5 bar at normal atmospheric
pressure (1.013 mbar) within the following limits:
- For group 1 fluids when DN is from 25 to 100.
- For group 2 fluids when DN is 125 and over.
In the event of any doubt, please contact Bardiani Valvole S.p.A.

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. Disposal must be in compliance with
local legislation.
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.

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");
A = Pneumatic power supply
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.

4. VALVE CONNECTIONS/CONNECTORS:
If the valve is fitted with connectors, you may proceed with installation.
Correctly insert the gaskets and tighten the connectors
.
5. WELDING THE VALVE BODY ONTO PIPING:
Remove the body from the rest of the valve before proceeding with
welding operations. Please refer to the following pages in this manual.
CAUTION!
Hand crushing hazard. During operation there is a risk of crushing
inside the valve body in the area between the actuator and the valve
body.
6. MINIMUM MAINTENANCE CLEARANCES:
Make sure there is enough room around the valve for it to be
disassembled (with the control unit installed).

8 Cleaning
1. VALVE CLEANING WITH DETERGENTS:
The system in which the valve is installed must be cleaned by expert
personnel in observance of the following:
- Abide by the indicated detergent concentration values;
- Observe the instructions provided by the detergent manufacturer.
- Always wear protective safety glasses and gloves.
IMPORTANT!
- Accurately dose detergents to avoid excessive concentration;
- Always rinse thoroughly with clean water after washing.
- Check compatibility of valve materials.
CAUTION!
Burns hazard. The valves and piping may be very hot. Wear protective
gloves
WARNING
After installing a new or serviced valve, perform an internal washing
cycle before using the piping for food liquids. If it there has been any
welding work, passivation treatment must be carried out.
EXAMPLE OF INTERNAL WASHING CYCLE (CIP)
Phases Temperature °C Washing product
Initial rinse Environment Chlorine- and chloride-free
water
Washing 70 °C Caustic soda (NaOH) at 1%
Intermediate rinse Environment Chlorine- and chloride-free
water
Washing 70 °C Nitric acid (HNO3) at 0.5%
End rinse Environment Chlorine- and chloride-free
water
Recommended washing product velocity = 2m/s
