DRIP, TRACER: The WD600S thermodynamic steam trap
is commonly used as a drip trap on steam mains and steam
supply lines. Supplied with integral strainer and optional
blowdown valve to protect the trap from contamination. These
traps can be used on tracing applications; however, thermostatic
traps are normally recommended for this service. Ideal for
outdoor applications that are subject to freezing and for
superheated steam conditions.
H O W I T W O R K S
The thermodynamic trap has cyclic on-off operation with a disc
that is pushed open by incoming condensate and closes tightly
when steam tries to escape.

3.5-600 PSIG (Not recommended for use below 10 PSI)
•
Suitable for superheated steam
•
Freezeproof when trap is piped in a vertical orientation
for complete drainage of condensate

Trap can be installed in any position; however, horizontal is
preferred. Installation should include isolation valves. Do not
weld or damage can occur to the seat area.

If trap fails, close isolation valves and remove cap. Clean disc
and seating surfaces and replace cap and disc with groove side
toward seat. NOTE: Do not over tighten cap. For full maintenance
details see Installation and Maintenance Manual.

An insulation cap is available to reduce cycle rates and steam
loss in rain, snow, or cold environments. Blowdown valve, used
for flushing dirt and scale from strainer.
