MAINTENANCE
7.1 Ordinary maintenance
7.4 Storage
Valves are boxed using a VpCi protective packing system, offering best protection to oxidation during components sea transport or long
storage in humid environments.
The valve surface is protected with a zinc coating, which guarantees a corrosion resistance of over 200 hours in the salt spray test.
Additionally all valves are tested with mineral oil ISO VG 46; the oil film left after testing ensure the internal corrosion protection.
For the valves transporting and storing always observe the environmental conditions specified in the relevant technical tables.
Improper storage may damage the product.
The valves can be stored for up to 12 months under the following conditions:
• If there is no specific information in the components technical tables, comply with a storage temperature of –20 °C to +50 °C
• Do not store the valves outdoors
• Protect the valves against water and humidity in case of storage in open air
• Store the valves in the shelf or on a pallet
• Store the valves in the original packaging or comparable packaging in order to protect them from dust and dirt
• Remove the plastic covers from the valves mounting surface only before the assembly
In case of storage period longer than 12 months please contact our technical office
