(e.g. EN1626 for shut-off valves and EN ISO 4126-1 for safety valves).
The technical service life can be restarted several times through the exchange of wearing parts within the
context of the maintenance intervals, and lifetimes of more than 10 years can be achieved.
If products are stored for a period exceeding 3 years, then the synthetic material components and
elastomer sealing elements fitted to the product should be replaced as a precautionary measure before
