tion temperature.
May be installed vertically, to drain trap
body when steam is off, to prevent freezing.
Compact size.
Easily serviced in line, replaceable seat
and disc (some models).
All stainless steel.
Will tolerate water hammer and superheat.
Disadvantages
Noise.
Sensitive to dirt, prevents tight closing
of disc.

Description
Thermodisc steam traps provide dependable
performance for applications with light to
moderate condensate loads. Thermodisc
traps are excellent for high pressure drip
and steam tracing applications.
Because the disc is the only moving part,
the traps are rugged and resistant to dam-
age. However, if the seat and disc require
servicing they may be easily replaced with-
out removing the trap body from the piping.
Applications
Steam tracer lines where maximum tem-
perature is required.
Outdoor applications including drips on
steam mains.
Drying tables.
Tire mold press and vulcanizing equipment
Dry kilns.
Pressing machines.
Rugged applications (superheat & water
hammer).
