Spirax Sarco Thermodynamic Steam Trap
The Thermodynamic steam trap cycles periodically to discharge condensate very nearto steam temperature. It is unaffected by
waterhammer or superheat.
Limiting Operating Conditions
Max. Operating Pressure (PMO)600 psig(42 barg)
Max. Operating Temperature800°F (427°C) at all operating
pressures
Minimum pressure for satisfactory operation is 3.5 psig, (0.24 barg).
Maximum back pressure should not exceed 80% of the inlet pressure
under any conditions of operation, otherwise the trap may not shut.
Pressure Shell Design Conditions
PMA 600 psig/up to 800°F 42 barg/up to 427°C
Max. allowable pressure
TMA 800°F/0-600 psig 427°C/0-42 barg

Typical Applications
Steam main drainage and tracer lines, process equipment, laundry and kitchen equipment, superheated steam applications, out door installations subject to freezing.
Installation
The preferred installation is in the horizontal position as close as
possibleto equipment being drained.Install strainer (20 mesh)
upstream and full port isolating valves upstream and downstream
of trap.Piping to and from the trap should be at least equal to or
one size larger than trap connection. Do not weld pipe connection
to trap.Body material is not suitable for welding.
For freeze resistant installations, all drains must be pitched toward
the trap for gravity flow.Trap must be installed vertically, dis
charging downward. Discharge piping must be self-draining.
