The regulator is maintenance free. Neverthe-
less, it is subject to natural wear, particularly
at the seat, plug and operating diaphragm.
Depending on the operating conditions, the
regulator needs to be checked at regular in-
tervals to detect and avoid possible malfunc-
tions.
CAUTION!
Make sure the relevant plant section has been
depressurized and, depending on the pro-
cess medium, drained as well before remov-
ing the regulator from the pipeline.
Check the filters installed in ports A and B (if
applicable) and clean them if necessary.
If you do not succeed in removing faults or
malfunctions yourself, contact SAMSON for
support (see section 5).
