CAUTION
Damage due to frost, humidity or dirt
Corrosion/contamination of the valve!
▷
Store the valve in a dry, dust-free and vibration-free, frost-proof room where
the atmospheric humidity is as constant as possible.
▷
Protect the valve against contamination, e.g. with suitable caps or film.
CAUTION
Damage due to excessive valve closing force
Damage to the seat/disc interface!
▷ Store the valve in the closed position.
▷ For soft-seated valves, ensure that the valve is closed using little force only. This
will prevent premature cold flow (compression set) of the thermoplastic
material.
Storage and/or temporary storage of the valves must ensure that even after a
prolonged period of storage the valves’ function is not impaired.
The temperature in the storage room must not 40 °C.
Cover the actuators to protect them from dust and dirt, and protect them from
mechanical damage.
If properly stored indoors, the equipment is protected for a maximum of 12 months.
New valves are supplied by our factory duly prepared for storage.
For storing a valve which has already been operated, observe the measures to be
taken for shutdown. (

3.4 Return to supplier
1. Drain the valve as described in the manual.
2. Flush and clean the valve, particularly if it has been used for handling noxious,
explosive, hot or other hazardous fluids.
3. If the valve has handled fluids whose residues could lead to corrosion damage in
the presence of atmospheric humidity or could ignite upon contact with oxygen
also neutralise the valve and blow through with anhydrous inert gas to ensure
drying.
4. When returning valves used for handling Fluids in Group 1 always complete and
enclose a certificate of decontamination.
Indicate any safety measures and decontamination measures taken.
NOTE
If required, a blank certificate of decontamination can be downloaded from the
following web site:
