CONSIDERATIONS OF TECHNICAL RISK
Adler S.p.A. ball valves, if provided of CE marking are manufactured in accordance with P.E.D. directive (97/23/EC) and/or ATEX directive (94/9/EC)
and/or machinery directive (98/37/EC), but they don’t consider in their design the following factors of risk:
1) Adler S.p.A.“Standard” ball valves can be used in a temperature range between –28.8 / + 250 °C. For service temperatures below – 28.8 °C ball
valves construction materials shall be submitted to an impact test at the minimum service temperature. For temperatures between – 28.8 °C &
+ 250 °C ball valves have to be provided with seats & seals able to withstand the temperature degree required (Adler S.p.A. technical support is
suggested to select the suitable seats & seal material).
2) Adler S.p.A.“Standard” ball valves are not equipped with devices suitable to avoid internal over-pressures caused by incorrect operations of
process or by fluids & liquids subjected to an increase of volume and/or pressure. (These devices, such as the over-pressure hole into the ball or
the safety relief seats are available upon request).
3) Adler S.p.A.“Standard” ball valves are not designed with special devices to withstand a sudden thermal jump (thermal Shock).
4) Adler S.p.A.“Standard” ball valves are not equipped with “Fire Safe” seals. (“Fire Safe” ball valves certified BS 6755 are supplied upon request).
5) In general Adler S.p.A.“Standard” ball valves are not mechanically designed to bear over loads due to exceptional atmospheric or natural
phenomenon’s (Ex. earthquakes).
6) In general Adler S.p.A.“Standard” ball valves are not designed to bear loads on flanges, on pipe connections or pipe-line.
7) In general Adler S.p.A.“Standard” ball valves can’t withstand with ice inside their bodies. (In this case user has to consider the optional stem
extension for insulating, avoiding the presence of residual product inside the valve).
8) Adler S.p.A. ball valves are suitable for low temperature service (up to – 196°C) when provided of cryogenic stem extension (available on
request).
9) Adler S.p.A. ball valves are suitable “industrial” oxygen service when supplied degreased and packed in polyethylene bags only.
N.B. For “medical” oxygen service please contact Adler S.p.A.
10) The compatibility between ball valves construction materials and mediums is selected by the user. Adler S.p.A.personnel are at your disposal for
additional technical aid, but the user is ultimately responsible for verifying the compatibility between medium and materials.

BALL VALVE START-UP
Before installing the ball valve on the pipe-line it is mandatory, for the user, to verify the compatibility of the ball valve with service conditions (medium,
temperature and pressure). With reference to standard ball valves stocked on shelves by wholesalers they will have to assure themselves about the
compatibility with the use conditions required by the customer. Alternatively with reference to the “consideration of technical risk”, they’ll have to ask to
Adler S.p.A. to suggest the suitable product for the specific utilization required.
Adler S.p.A. Ball Valves must be only used for on-off (fully open/ fully close) service.
It’s mandatory to consult Adler S.p.A. Technical Department before using ball valves for regulating service.
Before using the ball valve in a potential explosive atmosphere it’s necessary:
•to verify the compatibility between the ball valve and the zone in which the ball valves should be installed (see directive 99/92/CE);
•to foresee the pipe-line ground connection on which the ball valve should be installed;
•to check that the temperature of the ball valve surface is not higher than the flammable point of the atmosphere in which the ball valve is installed
(in this case foresee an insulating cover device for the valve and an extension for the wrench) ;
•before installing ball valves with welding ends to make sure that the process of welding is realized respecting all the safety norms the classified
zone requires;
•to avoid mechanical knocks during the installation that may cause sparks.
REMARK : Adler S.p.A. cannot be held responsible for damage caused by improper use or modification of the product.

BALL VALVE INSTALLATION
Before installation it is necessary:
•To verify that the rating marked on the body valve is higher than the working pressure;
•To be sure that the pipe-line is free from residual of weldings, rubbish, shavings and every kind of extraneous materials;
•To check for the absence of extraneous particles (ground, dust, etc.) in the passage, on seat and ball surface if ball valve has been stocked without
plastic caps of protection.
•To remove plastic caps of protection;
•To operate the ball valve twice (open and close);
•To verify if the weight or the dimension of the ball valve require more workers for transport and installation.
•Flanged ball valves need gaskets interposed between them and counter-flanges. (These gaskets are not supplied by Adler S.p.A.)
To assemble flanged ball valves to the pipe-line it’s necessary to use screws or stud bolts fixed by a torque meter key. The torque values are available on
“Table 1” and “Table 2”.
For split valves (three parts) with welding ends, set the valve on piping, make three welding point to fix the ends of the valve, unscrew and remove
tie-rods and then slip off the central body of the valve. Finally complete the welding and reassemble the body valve.

WARNING : diagrams and pictures are provided as example for your assistance; the manufacturer may make any changes which he considers
appropriate, without any prior warning, in line with his aim of pursuing a policy of constant development and innovation.
BALL VALVE MANTEINANCE
Considering working conditions, after a certain period of work and operations the ball valves may have problems of tightness due to seats & seals
settlement. Small leakage from the stem can be solved adjusting stem bolt. We suggest this operation once a year.
With reference to pictures of ball valves proceed as follows:
Unscrew and remove the first nut (Ref. 14) up to allow a slight vertical movement of the lever (Ref. 15), without removing it from it’s site. Then tighten
with an hexagonal key the under-placed nut (Ref. 14) keeping the lever (Ref. 15) locked by the hand. Screw the top nut to take the ball valve back to
initial position.
If the leakage persist we suggest servicing the ball valve dismounting it from the pipe-line replacing seats & seals.
WARNING : to order spare parts is always necessary to know the model of the valve, the nominal diameter, material and possible serial number.
To avoid damages to people or things before to service, the ball valve must be depressurised. Then follow these indications:
-Turn the lever (ref. 15) to 45° so the ball is opened (or closed) at 50%;
-Clear-up the pipe-line on which the ball valve is mounted;
-Take the necessary precautions to avoid possible accident. During operations of disassembly wear always appropriate clothes & shoes, anti-acid rubber
gloves, glasses, powder/gas-mask evaluating the degree of danger of the medium.;
-Wash accurately the ball valves;

TROUBLE SHOOTING
PROBLEM CAUSE
- Internal medium
leakage
- Ball valve working conditions guaranteed by the manufacturer, have not been respected.
- Ball valve has been damaged by chemical corrosion due to the incompatibility occurred
between construction materials and medium.
- Damaging of seats & seals or ball surface due to foreign particles (ground, dust, etc...).
- Internal seats & seals are wear out: it’s necessary to recondition the ball valve .
- External medium
leakage
- Ball valve working conditions guaranteed by the manufacturer, have not been respected.
- Ball valve has been damaged by chemical corrosion due to the incompatibility occurred
between construction materials and medium.
- Presence of contaminating substances into the medium.
- Stem and closure seals are wear out missing a periodic recondition.
- Union body/ end screws of the ball valve work loose or are stretched due to a wrong
installation of the ball valve between flanges of pipe-line (Ex. Not in axis, bending) for the
lack of an expansion-reproaching device or the presence of heavy vibrations on the pipe-
line.
- The ball valve has an
excessive torque or the
ball is locked
- Ball valve working conditions guaranteed by the manufacturer, have not been respected.
- Possible changing state of the medium inside the ball valve.
- Possible particles precipitation on external ball surface that causes a mechanical
interference during the rotation of the ball.
DISPOSAL (OF VALVES)
The ball valves to be discarded must be removed from the pipe-line as follows:
•Turn the lever (Ref. 15) to 45° so the ball is opened (or closed) at 50%;
•Clear up the pipe-line on which the ball valve is mounted ;
•Turn the lever opening the ball at 100%;
•If possible wash the pipe-line;
•During this operations take the necessary precautions compared to the degree of danger of the medium: wear
always appropriate clothes & shoes, anti-acid rubber gloves, glasses, powder/ gas mask.
•The ball valve dismounted from the pipe-line must be washed accurately. If this procedure is not executed the
medium into the ball valve may be dangerous for people and cause ambient pollution.
After having washed the ball valve it is necessary to make the separation between Re-cycling components (metals) and
components to be treated as “special wastes” (gaskets in P.T.F.E., Viton, Grafoil etc ...). This operation is essential .
To dispose of the ball valve without observing this procedure will cause serious ambient pollution.
WARNING : Adler S.p.A. cannot be held responsible for disposal executed without the observance of the norm.
