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.

Pressures To 250 PSIG (17.2 barg)
Temperatures to 450°F (232°C)
Freeze Proof — When installed on side with cover
perpendicular to ground.
Renewable In-line — Renew trap in-line with factory
packaged precision matched internal parts, replacement
kits.
Compact — Requires minimum space while providing
condensate capacities equal to larger mechanical traps.
Superior Performance — Maximum air handling
capability. Immediate response to changing pressure and
condensate loads. No adjustment necessary.
Sensitivity — Increased when installed on side with
cover perpendicular to ground.
Temperature Sensitive Actuators — One moving part,
stainless steel, fail open or closed, welded actuator
provides maximum corrosion, thermal and hydraulic
shock resistance and sensitivity.
Guaranteed — Guaranteed against defects in materials
or workmanship for 3 years.

SPECIFICATION
Steam trap shall be of balanced pressure design with stainless
steel welded actuator capable of discharging condensate within
10°F of saturated temperature. Where greater sensitivity is
required or protection from flash steam locking, a SLR orifice will
be available to allow condensate and flash steam evacuation at or
near saturated temperatures. Thermostatic actuator shall employ
a conical valve lapped in matched sets with the seat ring assuring
tight shut off. Trap shall be cast iron or cast steel bodied suitable
for pressures to 250 psig and available in 1/2" through 2" NPT.
MAXIMUM OPERATING CONDITIONS
PMO: Max. Operating Pressure 250 psig (17.2 barg)
TMO: Max. Operating Temperature 450°F (232°C)
PMA: Max. Allowable Pressure 250 psig (17.2 barg)
TMA: Max. Allowable Temperature 450°F (232°C)
