Australian Pipeline Valve don’t consider in our design the following factors of risk:
1. Australian Pipeline Valve ‘Standard’ ball valves can be used in a temperature range between -28.8 to +200°C. (Note,
pressure limitations apply above 38°C refer to Pressure/Temperature charts.) For service temperatures below -28.8°C
ball valve construction materials shall be submitted to an impact test at the minimum service temperature. For
temperatures outside of the range of -28.8°C to +200°C ball valves have to be provided with seats, seals and body
material able to withstand the temperature degree required.
2. The onus is on the customer to specify all materials of construction and service conditions. Australian Pipeline Valve shall
assume standard materials and conditions if not otherwise specified.
3. Australian Pipeline Valve ‘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 in the ball or safety seats are available upon request).
4. Australian Pipeline Valve ‘Standard’ ball valves are not designed with special devices to withstand a sudden thermal
jump (thermal shock).
5. In general Australian Pipeline Valve ‘Standard’ ball valves are not mechanically designed to bear overloads due to
exceptional atmospheric or natural phenomenon’s (such as earthquakes).
6. In general Australian Pipeline Valve ‘Standard’ ball valves are not designed to bear loads on flanges, on pipe connections
or pipeline.
7. In general Australian Pipeline Valve ‘Standard’ ball valves can’t withstand ice inside their bodies (in this case user must
specify the optional stem extension for insulating, avoiding the presence of residual product inside the valve).
8. Australian Pipeline Valve ‘Standard’ ball valves are not suitable for low temperature service below -29°C (-20°F) unless
provided with cryogenic stem extension and other modifications (available on request).
9. Australian Pipeline Valve ‘Standard’ ball valves are suitable for ‘industrial’ oxygen (not medical) service when supplied
degreased and packed in polyethylene bags only.
10. The compatibility between ball valves construction materials and medium is selected by the user. The user is ultimately
responsible for verifying the compatibility between medium and materials.
11. Abrasive or dirty service, high temperature service, low temperature service, vacuum service, near zero pressure service
and other special applications should be clearly stated when requesting quotation.
BALL VALVE START-UP
Before installing the ball valve onto 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 held in stock the reseller and
end user will have to assure themselves of the compatibility with the use of conditions required by the customer. Australian
Pipeline Valve ball valves must be only used for on-off (fully open/fully closed) 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 valve should be installed.
• To foresee the pipe-line ground condition 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 specify 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 carried out in accordance with
all the safety requirements of the classified zone.
• To avoid mechanical knocks during the installation that may cause sparks.
Australian Pipeline Valve cannot be held responsible for damage caused by use of the product especially if it is improper use or
modified.
