Design and principle of operation
line. The bypass ensures that the plant does
not need to be shut down for service and re-
pair work on the valve.
Insulation
Control valves can be insulated to reduce
heat energy transfer.
Refer to the instructions in the 'Installation'
section.
Safety guard
For operating conditions that require in-
creased safety (e.g. in cases where the valve
is freely accessible to untrained staff), a safe-
ty guard must be installed to rule out a crush
hazard arising from moving parts (actuator
and plug or piston stem). Plant operators are
responsible for deciding whether a guard is
to be used. The decision is based on the risk
posed by the plant and its operating condi-
tions.
Noise reduction
Trims with flow divider ST 1 can be used to
reduce noise emission (
u
T 8081).

Noise emissions
SAMSON is unable to make general state-
ments about noise emissions. The noise emis -
sions depend on the valve version, plant fa-
cilities and process medium.
