Design and principle of operation
3.3 Additional ttings
Refer to the instructions in the 'Installation'
section.
Strainers
We recommend installing a SAMSON
Type2NI Strainer upstream of the valve. It
prevents solid particles in the process medi-
um from damaging the valve.
Bypass and shut-off valves
We recommend installing a shut-off valve
both upstream of the strainer and down-
stream of the valve and installing a bypass
line. The bypass ensures that the plant does
not need to be shut down for service and re-
pair work on the valve.
Insulation of cold systems
Control valves can be insulated to reduce
heat energy transfer.
The insulation thickness depends on the me-
dium temperature and the ambient condi-
tions. 50mm is a typical thickness.
Noise reduction
The Type3214 Globe Valve can be tted
with a ow divider ST1. Refer to Data Sheet
u T8081.
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 on control valves
with a yoke to rule out a crush hazard aris-
ing from moving parts (actuator and plug
stem). Plant operators are responsible for de-
ciding whether a guard is to be used. The
decision is based on the risk posed by the
plant and its operating conditions.
3.4 Technical data
The nameplates on the valve and actuator
provide information on the control valve ver-
sion. See the 'Markings on the device' sec-
tion and the associated actuator documenta-
tion.
More information is available in Data Sheet
uT5868-1.
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.
