Storage:
If longer storage time is expected, the Hydranor valve must be kept in a dry room free from dust. Sudden large temperature variations must be avoided. For storage longer than one year, the valve must be filled with inhibition oil. Before use check all visible seals and flush with clean oil.
Delivery:
The Hydranor valves are supplied in assembled configurations, with sealing 'O-rings'.
Fixing screws and spare parts must be ordered seperately.
