SPIRAX SARCO SIGHT CHECK IM-P022-02 (COMBINED SIGHT AND CHECK VALVE)
NEW ITEM IN ORIGINAL BOX!!!!!!!!!! 1 YEAR WARRANTY MRO
A sight check is a combined sight glass and
check valve. It is used to observe discharges
from steam traps. The position of the ball check
indicates whether or not condensate is flowing.
Where condensate rises after the trap it
eliminates the need for a separate check valve
thus simplifying installation.
It is particularly useful for commissioning steam
traps fitted with steam lock release (SLR).
It can also be used on other liquid lines for which
the materials of construction are compatible.
Maximum operating pressure 3.6 bar g
Maximum operating temperature 148
Cold hydraulic test pressure 7 bar g
Sight checks can be fitted in either a horizontal
or a vertical line on the outlet side of a steam
trap. Where the trap is a blast discharge type
e.g. thermodynamic, the sight check must be
fitted at least 1 m from the trap. This is to ensure
that the glass tube is not subjected to thermal
shock or pressure. Reasonable steps should
be taken to protect personnel from injury in the
unlikely event that the glass breaks.
Ensure access is available to enable the
withdrawal of the discharge tube.
All work must be carried out by a suitably
competent person. Before starting work
ensure that suitable tools are available and the
'Safety information' overleaf is being complied
with. Use only Spirax Sarco replacement parts.
Before carrying out any work on this equipment
make sure that it is fully isolated (see 'Safety
information' overleaf). After maintenance
ensure that the system is fully functioning.
Undo bolts. Remove cover and sight tube.
Take out old gaskets and carefully clean out
recesses. Fit new gaskets supplied with sight
tube and reassemble, tightening bolts evenly
do up the bolts little more than finger tight,
retightening as necessary after a period of
Remove cover and sight tube the same way as
'To renew sight tube', and lift out ball check.
Using notches, carefully unscrew old tube and
fit new one. Renew gaskets, fit new ball check
In some applications condensate
can act as a solvent for glass. It is recommended
that the sight tube is periodically checked for
thinning. If there is any evidence of thinning
then the sight tube should be replaced
