Design and principle of operation
Shut-off valves
We recommend installing a shut-off valve (1
and 6) both upstream of the strainer and
downstream of the regulator. The shut-off
valves ensure that the entire plant does not
need to be shut down for service and repair
work on the regulator.
Insulation
Regulators can be insulated to reduce heat
energy transfer.
Refer to the instructions in the 'Installation'
section.
3.2 Technical data
The regulator nameplate provides informa-
tion on the regulator version (see the 'Mark-
ings on the device' section).
More information is available in Data Sheet
u
T 2551-1.
Compliance
The Type 33-1 Regulator bears both the CE
and EAC marks of conformity.
Leakage class
The soft-seated regulator has the leakage
class IV according to IEC 60534-4.
Note
Type test
The device has been typetested as a safety
shut-off valve (SSV) by the German
Technical Inspectorate (TÜV) according to
the requirements stipulated in the AGFW
(German District Heating Association)
document FW 504.
The test mark is available on request.
Process medium and scope of application
The Type 33-1 Safety Shut-off Valve with
Pressure Reducing Valve is used to maintain
the pressure downstream of the valve to an
adjusted set point.
− Suitable for gases and liquids
− Max. temperature 150 °C
− Set points from 1 to 10.5 bar
− Valve size DN 65 to 250
− Pressure ratings from PN 16 to 40
The regulator is open when relieved of pres-
sure. The valve
closes when the downstream
pressure rises.
Temperature range
Depending on how the regulator is config -
ured, it can be used up to temperatures of
150 °C (see Table 3-1). The minimum tem -
perature is limited by the accessories used
and the actuator's diaphragm material
(
u
T 2551-1).
Noise emission
SAMSON is unable to make general state-
ments about noise emissions. The noise emis-
sions depend on the regulator version, plant
facilities, process medium and operating
conditions.
