Samson 3595, Mounting And Operating Instructions

3-4 EB 8079 EN
Design and principle of operation
The basic pneumatic actuator can be re -
placed by an actuator with additional
handwheel, an electric actuator or an hy-
draulic piston actuator.
Bellows seal
The valve can be fitted with a bellows seal to
meet special requirements resulting from the
process medium used.
3.3 Additional fittings
Strainers
We recommend installing a SAMSON
strainer upstream of the valve. It prevents sol-
id particles in the process medium 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 line ensures that the plant
does not need to be shut down for service
and repair 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, which 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 stem). Plant operators are responsi-
ble for deciding 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.
Further technical data for the valve are
available in the Data Sheet
u
T 8079, for
actuators in the associated data sheets, for
example
u
T 8318 for Type 3276 Actuator
or
u
T 8310-X for Type 3271 Actuator.
Noise emissions
SAMSON is unable to make general state-
ments about noise emissions. The noise emis-
sions depend on the valve version (e.g. with
cage), plant facilities and process medium.
