be used with this pipeline connector enabling it to be tailored to suit any application:
-
UTD30
and
UTD52
thermodynamic steam traps.
-
UBP32
balanced pressure steam trap.
-
USM
bimetallic steam trap.
-
UFT32
ball float steam trap.
-
UIB30
and
UIB30H
inverted bucket steam traps.

or WLSL1 with DIODE
for use with RI6C are available as optional extras, to enable
operational monitoring of the steam trap.
Please note
that the optional Spiratec
SSL1
and
WLSL1
sensors
must not be fitted when the STS17.2 is installed in a vertical application
.
However a sensor can be fitted to a UTD30 steam trap if fitted.
BDV1 blowdown valve
is also available for cleaning the strainer during operation.
Care should be taken when using the BDV1 blowdown valve as the discharge may be hot.
Please note that a BDV1 cannot be used when a Spiratec sensor has been chosen to be
part of the unit.
Retrofit double isolation valve and spool piece
to convert a single upstream isolation
version to double isolation.
Insulation jacket
is available to reduce heat loss and energy wastage. See separate literature.
