Special storage instructions for soft parts
Soft parts, e.g. actuator diaphragm
−
To keep soft parts in shape and to pre-
vent cracking, do not bend them or hang
them up.
−
We recommend a storage temperature of
59 °F (15 °C) for soft parts.
− Store soft parts away from lubricants,
chemicals, solutions and fuels.

4.4 Preparation for installation
Proceed as follows:
Î
Flush the pipelines.
The plant operator is responsible for clean-
ing the pipelines. Observe the maximum
permissible pressure for both the valve and
plant.
Î
Check the valve to make sure it is clean.
Î
Check the valve for damage.
Î
Check to make sure that the type desig-
nation, valve size, material, pressure rat -
ing and temperature range of the valve
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.).
Î
For steam applications, make sure that
the pipelines are dry. Moisture will dam -
age the inside of the valve.
Î
Check any mounted pressure gauges to
make sure they function.
Î
When the valve and actuator are al -
ready assembled, check the tightening
torques at the bonnet. Components may
loosen during transport.
