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.
6.2.1 Regulation of liquids
To start up the excess pressure valve, open
shut-off valves
slowly
.
Î
For medium temperatures above 150 °C,
first fill the compensation chamber with
the process medium.
6.2.2 Regulation of steam
Unscrew filler plug (19) on the compensation
chamber (18). Use the included plastic fun-
nel or a jug to pour in water until it starts to
overflow. Screw the filler plug back in and
tighten it.
Î
All pipes conveying the process medium
must be completely drained and dry.
Î
Air and condensate must be allowed to
escape from the plant.
Î
Allow time for the pipes and valves to
heat up.
