The STS17.2 compact pipeline connector steam trapping station

has been designed to provide a convenient ready to install trapping

solution, which includes: upstream and downstream isolation

valves (2), body incorporating quickfit connector + strainer (1) and

check valve blanking plug (16).

Available types

The STS17.2 is available with either single or double upstream

isolation.

The STS17.2 trapping solution incorporates Spirax Sarco

quickfit technology, which allows speedy trap maintenance.

The following swivel connector steam traps (sold separately) can

be used with this pipeline connector enabling it to be tailored to suit

any application:

Integral sensor type SSL1 (steam only) or WLSL1 (for

waterlogging) for use with R1C 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.
