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.

Temperatures to 400°F (204°C)
Temperature Sensitive Actuator — One moving part
stainless steel welded actuator for maximum corrosion,
thermal and hydraulic shock resistance.
Improved Energy Savings — Maximum elimination of air
and non-condensibles–trap closes at saturated steam
temperature.
Compact — Requires minimum space and provides
condensate capacities equal to larger mechanical traps.
Freeze Proof — Type A with horizontal inlet and vertical
outlet. Type AHV when installed vertically (outlet down) or
horizontally on side (cover perpendicular to ground).
Renewable In-line — With factory packaged, precision
matched internal parts kits.
Superior Performance — Fast response to changing
pressure and condensate loads. Maximum air handling
capability.
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, SLR orifice and Sterilizer trim shall be available to allow
condensate 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. A minimum of two
orifice sizes shall be available allowing for custom capacity sizing.
Trap shall be bronze bodied suitable for pressures through 200
psig and available in 1/2" through 1" NPT connections.
