Max PS Valve
body/differential: 10/10 BAR
Ser.No: Serial number consisting of
year – individual no - order number.
CE-marking when applicable.
These labels must not be removed, over coated or otherwise covered.
"Max. PS Valve body" which is marked on the label (see above) is max. allowed pressure when the valve
is open. Max. allowed pressure on closed valves may be lower and is marked on this label as well.

A5 Transport, storage and handling
Note
Additional requirements may be found in the actuator instruction, if any.
Storage and transport:
The valves are delivered with gate in, for the valve type, correct position during storage to ensure its function and to
protect the polished surface of the gate. Store the valve in a clean and dry environment and protect it against dirt,
dust and other contamination. Do not expose the valve to direct sunlight. If the valve is stored outside, it shall be
wrapped tightly in a plastic foil or similar to protect it against moisture or any dirt contamination. It should also be
stored high enough without any risk to be covered in snow or enclosed by water.
The valve has been packed according to the terms of delivery. It is important to make a visual inspection
at arrival. If transport damage is detected, report to the transportation company.
Handling:
Lifting and moving shall be carried out with soft straps. Place and
fasten the soft strap on the valve body as shown in fig.1, ensure that
the valve is properly balanced before lifting. Make shure that all
equipment is designed to hold the weight of the valve.
Never place lifting equipment:
• On the actuator, accessories or gate guards.
• In the bore of the knife gate valve, since it causes damages to the seat and retainer ring.
