Maximum Allowable Pressure
250 psig / 17.2 barg
1. Add (-HC) at the end of type number for high capacity.
2. The pressure/temperature limits in this Instruction Manual and any applicable standard or code limitation should not be exceeded.
Principle of Operation
Thermal actuator is filled at its free length with a liquid
having a lower boiling point than water. On start-up,
valve is normally open. When steam enters trap,
thermal actuator fill vaporizes to a pressure higher
than line pressure. This forces valve into seat orifice
to prevent any further flow. As condensate collects,
it takes heat from thermal actuator, lowering internal
pressure. Line pressure will then compress thermal
actuator to open valve and discharge condensate.
Valve opening automatically adjusts to load conditions
from minimum on very light loads to full lift at
maximum load.
Installation

WARNING
Personal injury or system damage may
result if this steam trap is installed,
without appropriate overpressure
protection, where service conditions
could exceed the limits given in the
Specifications section and/or steam
trap nameplate.

Additionally, physical damage to the
steam trap may result in personal injury
or property damage due to escaping of
accumulated gas. To avoid such injury
and damage, install the steam trap in a
safe location.
All pressure equipment should be
installed in a non-seismic area;
should not be exposed to fire; and
should be protected from thunderbolt
(lightning) strikes.
1. Before installing trap, blow steam through
equipment and piping to remove scale, pipe
threading chips and other dirt.
Emerson Thermostatic Bellows Traps do
not require change of body or cover for
different pressures.
2. Check arrows on trap body or cover to ensure
that flow direction is correct. See Figure 2 for
recommended installation.
