Installation
5.4.2 Bypass and shut-off
valves
– Install a hand-operated shut-off valve (1)
both upstream of the strainer and down-
stream of the regulator to be able to shut
down the plant for cleaning and mainte-
nance and when the plant is not used for
longer periods of time (see sec-
tionFig.7).
– The bypass ensures that the plant does
not need to be shut down for service and
repair work on the regulator.
5.4.3 Insulation
Toinsulatecoldsystems,werecommendrst
llingtheplantandcarefullyrinsingit.The
regulator must not yet be insulated at this
stage.
1. Start up the plant and adjust the set
point.
2. Shut down the plant again and let it heat
up until the condensation water has
dried off.
3. Insulate the regulator and pipes convey-
ing the process medium using insulation
material with a water vapor barrier. If a
control line is to be routed through the
insulation, special care must be taken
with the sealing since slight changes in
shape may occur. The insulation thick-
ness depends on the medium tempera-
tureandtheambientconditions.50mm
is a typical thickness.
5.4.4 Pressure gauges
– Install a pressure gauge (3 and 5) both
upstream and downstream of the regula-
tor to monitor the pressures prevailing in
theplant(seeFig.7).
