Start-up and operation
6.2 Starting up the plant
Î Start up the regulator after mounting all
parts. Make sure the control line is open
and correctly connected.
Î Open the shut-off valves slowly prefera-
bly starting from the upstream pressure
side. Afterwards, open all the valves on
the consumer side (downstream of the
regulator).
Î Fill the plant slowly with the process me-
dium. Avoid pressure surges.
Î Make sure that the pressure rises simulta-
neously upstream and downstream of the
regulator to avoid damaging the balanc-
ing bellows.
