5.1 Installation conditions
5.1.1 Depending on the ver-
sion
Type 3381
The single attenuation plate is mounted be-
tween the valve or a pipe expander and the
pipe flange using suitable gaskets.
Type 3381-1R
The single attenuation plate with reduced di-
ameter and possibly reduced thickness is
clamped between the valve or a pipe ex -
pander and the pipe flange using suitable
gaskets.
Type 3381-3-X
Two to five attenuation plates are installed
one after the other in a housing. The nominal
sizes of the inlet and outlet can vary: the no -
minal inlet size of the housing corresponds
to the nominal valve size. The nominal outlet
size corresponds to the downstream nominal
pipe size. A pipe expander is already integ
-
rated into the housing.
The Type 3381-3-X Silencer is bolted to the
control valve using a suitable gasket before
they are both installed into the pipeline using
suitable gaskets.
Type 3381-4-X
Two to five attenuation plates are clamped
between the valve outlet or pipe expander
and the pipeline (wafer-type version) using
suitable gaskets.
A pipe expander must be installed if the no -
minal size of the attenuation plates is larger
than that of the valve.
5.1.2 Support and suspension
The plant engineering company is responsi-
ble for selecting and implementing a suitable
support or suspension of the installed control
valve including silencer and the pipeline.
