Transportation
To prevent damage and serious injury during transportation of the valve:
•
Only suitable and perfect load suspension devices and lifting tackle should be used.
•
Take the weight of the valve into account when selecting the load suspension device and lifting tackle.
•
Transportation routes are to be blocked and clearly marked so that unauthorized persons cannot enter the
danger area.
•
Transportation work should only be carried out by qualified and authorized persons wearing suitable protection
clothes.
To prevent damage of the valve:
•
The transportation of the valves to their final destination (building site) must be done in a solid box adapted to
the size of the valve taking into account the type of transport as well as any applicable regulations.
•
The valves must be suitably protected against external damage and atmospheric effects.
•
Depending on the duration of transportation and storage and also with regard to the climatic conditions,
preservation must be made by means of gas treatment or by shrink-wrapping and sealing the valve in
polyethylene film that also has an adequate amount of a desiccant such as silica gel placed inside.
Storage
•
The valves should be stored indoors in a dry place until final installation. All working parts must be suitably
covered to protect them against humidity, dust or other soiling.
•
Temperatures for storing: - 15°C to + 30°C
•
In humid rooms drying material respectively heating is necessary to avoid condensation of water.
•
During a longer period of storage or in the case of unfavourable storage conditions that might affect subsequent
functioning, all metallic bright surfaces such as the spindle, piston rod, and sealing surfaces must be effectively
protected against corrosion by means of a suitable and durable corrosion preventative.
•
The corrosion preventative applied at the factory must be checked for any damage in transit and suitably
repaired if needed.
•
Valves have to be protected against force (shock, blow, vibration etc.).
•
During storage or transport the ball valve must be either in open or closed position (no intermediate position!).
•
For parts mounted on the valves, such as electrical actuators, limit switches, valves, etc., the corresponding
storage instructions of the relevant manufacturers shall have priority.
Valve housing coating
Danger:
The coating of the valve housing has been designed in such a way as to prevent danger due to static
charge. For this reason, no changes may be made to the coating of the valve housing. If the coating of the valve is
changed, ignitable discharge could occur as a result of static charge.
Actuators
Note: actuators and accessory parts mounted or provided by the customer (e.g. solenoid valves) must correspond
to the outer device category of the valve (3D, 3G, 2D or 2G).
