Storage instructions

Handling

The handling of the valve has to be made with care, in order to avoid any shock, even accidental, which could damage it. In particular any lift of the valve should be carried out paying attention that the chain, cable or rope used for that specific operation is not clamped or does not touch the shafts, the gearbox or its handwheel. For this task the ends of the valve body or the flanges should be used. It is absolutely forbidden to use the eventual hook(s) of the actuator to lift the valve.

Storage

Generally the valves are supplied with plugs at the extremities, or in pallets banded with plastic film; if the valves are without packing and have to stay for long time in the stock before being install, they must be stocked covering the passage of the valve, safeguarding in this way the interior parts and particularly the seat from the contact with powder or dirt.

The valves must be stored in a location offering a good protection against the direct sun, the rain and all other atmospheric elements. In absence of a right place the valves have to be wrapped with a cellophane or plastic sheet, if possible of dark color.

The valves must not weight on the shaft or on the gearbox, and if the valves have to be stacked one on the other, it's important to pay attention that the coated surfaces doesn't come directly in contact: a cardboard between the surfaces should be used.

Accessories and spare kits storage

1- Gasket

Normally the seal ring of the disk is made with a rubber quality which is sensitive to the sunlight. Therefore it is usual to store such rubber part in an area protected from the sunlight, in order to avoid its deterioration. If such conditions are not available, rubber parts should be then at least protected by cellophane or plastic sheets of dark color.

2-Bolts

The requested flange bolting is normally packed in a sack or a box equipped with a tag indicating the number and the type of the packed bolts. It is absolutely necessary to keep them in the original condition of delivery, avoiding putting them in contact with material which could damage them. Generally the bolting is slightly lubricated before delivery; any contact with dirt or dust could, in extreme cases, damage the threads and prevent its future mounting.

3-Actuators

For this particular type of accessory, which is generally mounted on the valve at the time of the delivery,, it is necessary to pay attention that nobody, with the exception of the specialist or authorized people, could attempt to repair or manipulate it, this would take out any warranty covering these specific components. It is very important to check that the threaded orifices permitting the future electric/hydraulic/pneumatic connections are always well protected with the original plugs until their use in final assembly. This will insure that no dirt, dust, humidity or any other external particle will damage the internal parts (gears, electrical coils, pistons, cylinders, seats, etc.).

When the electrical wiring is not made immediately after the mechanical mounting of the valve in the pipe system, the installer/contractor will take the necessary measure to protect correctly and thoroughly the actuator against any atmospheric degradation and the built-up of condensation. Furthermore it is necessary to check periodically during this particular period of time the status of internal components, by removing the covers of the operative unit and of the reduction unit, protecting with silicone or oil vaseline the respective cover gaskets when remounting them.
