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

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.

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).
1 = Opening
2 = Top lift
3 = Bottom lift
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.

4. VALVE CONNECTIONS/CONNECTORS:
If the valve is tted with connectors, you may proceed with installation.
Correctly insert the gaskets and tighten the connectors.
5. WALDING THE VALVE BODY ONTO PIPING:
1. Blow air into the central union
2. Remove the body from the rest of the valve before proceeding
with welding operations.
CAUTION!
Hand crushing hazard. During operation there is a crushing hazard
caused by the washing pin or the guide pin (when present).
6. VALVE RIGHT INSTALLATION:
To guarantee its drainability, make sure the valve is in a vertical
position

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;

-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.
