Measures for preparation
− Make sure that the ambient air is free of
acids or other corrosive media.
− The permissible storage temperature of
standard control valves is –20 to +65°C
(–4 to +149°F).
Contact SAMSON's After‑sales Service de-
partment for the storage temperatures of oth-
er valve versions.
− Do not place any objects on the control
valve.
Special storage instructions for elastomers
Elastomer, e.g. actuator diaphragm
− To keep elastomers in shape and to pre-
vent cracking, do not bend them or hang
them up.
− We recommend a storage temperature of
15°C (59°F) for elastomers.
− Store elastomers away from lubricants,
chemicals, solutions, and fuels.
SAMSON's After‑sales Service department
can provide more detailed storage instruc-
tions on request.
4.4 Preparation for installation
Proceed as follows:
Î Flush the pipelines.
The plant operator is responsible for clean-
ing the pipelines in the 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 of the bolted joints (uAB0100).
Components may loosen during trans-
port.
