GENERAL WARNING
-The manual buttery valve model “VVF” not being safety valves cannot be used for the interception of explosive
substances, inammables, toxic or combustible products.
-They must be used within the specied pressure ratings for this type of valve.
-Read carefully the enclosed manual before installing, use and maintenance of the said valve
-Operators who come into contact with the valves must wear the appropriate protective clothing includinggloves and safety glasses.
-The installation of the valve must be carried out exclusively by specialised personnel following the instructionsin the manual on
installation and maintenance.
-Should there be a delay for a certain period of time from when the valve was purchased to the installation of the valve, keep the
valvecovered in a place out of harm and away from atmospheric agents until the installation.
-Do not use parts of the valve for other uses than those it was designed for.
-Make sure that all persons involved in the use of the valves have been trained and know well all the relative instructions in
this manual
-Before starting the commissioning process make sure that all object, tools and various objects that could possibly disturb the
operation of the valve have been removed.
-Do not permit unqualied persons to carry out maintenance and make sure that personnel involved know well the section in
the manual regarding maintenance procedures.
-Always use original spare parts from “BARDIANI VALVOLE S.P.A.” when replacing damaged or worn parts.

pLANNED MAINTENANCE
VALVE SpECIFICATIONS:
- Max. working pressure :
10 bar (145 psi) DN15--100
8 bar (115 psi) DN125
6.5 bar (94 psi) DN150
- Min. working pressure : Vacuum
- Max. product temperature : 120 °C (284 °F)
- Min. product temperature : -10 °C (14 °F)
- Material in contact with the product : AISI 316L (1.4404)
- Gasket in contact with the product (FDA homologation): EPDM, FKM, MVQ(silicon), HNBR (other seals avaiable upon
request).
- Finish on surfaces in contact with the product : Ra 0.8 µm (other types of surface nish upon request).
HANDELING
Based upon the weight of the valve it is necessary to use the appropriate carrying and restraining equipment (mobile
crane, fork lift, pump truck, etc.)
INSTALLATION
The valve must be tted to the installation in such a way as not to cause exing or torsion loads due to the weight of the
valve. It is advised to connect to the installation using tube work and materials at least consistent with the characteristics
equal to the valve itself.
USE
The opening and closing of the valve must be done slowly in order to avoid shock waves /air locks in the installation in
which the valve is tted.
MAINTENANCE!
Make sure before carrying out any maintenance work that the installation to which the valves
are connected is isolated, and that there are no liquids remaining, and that the installation is not
pressurised.
The normal maintenance consists of the replacement of the seals present within the valves.
PROBLEM POSSIBLE CAUSE POSSIBLE REMEDY
External leakage Worn out gasket Repalce gasket
Internal lekage with closed valve,
caused by normal wear
External lekage Too high pressure Repalce with gasket of different
elastomer type
Too high temperature
Internal with closed valve occuring
earlier than normal wear
Aggressive uids Modfy opeation conditions
Too many active control
Difcult opening Incorrect elastomer type of gaskets Replace with gasket of different elastomer type
PLANNED MAINTENANCE VALVE GASKETS
Preventive Replace after 12 months
In case of leakage Replace at the end of the day
Periodical Check for correct operation and absence of
leakage
Record all actions taken
SCrAppING AND DISpOSAL
For the scrapping of the valve proceed as follows:
-Disassemble all the valve’s components in order to separate it’s materials.
Before starting the mechanical scrapping procedure wash carefully all the parts of the valve.
The principal parts of the valve are:
VALVE BODY: AISI 316L (4404)
SHUTTER: AISI 316L (4404)
ELASTOMETER: EPDM, FKM, SILICONE
For the scrapping of the valve the above listied materials are subject to the individual laws governing of the
countries in which the valves are to be scrapped.
