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 to discharge air,
non-condensibles and condensate. 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.

STEAM TRAPS
Pressures To 150 PSIG (10.3 barg)
Temperatures to 366°F (186°C)
Stainless Steel Body—Body materials of all models are
Type 316L Stainless Steel.
Self Centering Valve—Leak tight shut off. Assembly of
actuator and valve to impingement plate allows valve to
self-align with center of valve seat orifice. Provides long
lasting valve and seat.
Temperature Sensitive Actuator—316L Stainless welded
actuator for maximum corrosion, thermal and hydraulic
shock resistance. One moving part.
Thermal and Hydraulic Shock Resistant—Impingement
plate plus welded construction prevents damage to actuator.
Long Life Valve and Seat—Stainless steel valve and seat
matched together for water tight seal.
Maintenance—All models are sealed and maintenance
free.
Directional Discharge—Erosion prevented by directing
discharge into the center of pipe or tubing.
Best Air Handling Capacity—Fast start up and operation.
Fast Response—Quickly adjusts to condensate load or
temperature changes.
One Size Suits Most Services—Universal hygienic clamp
fits both 1/2" and 3/4" piping.
Two Year Guarantee—Trap guaranteed for two years
against defects in material or workmanship.

SPECIFICATION
Steam trap shall be thermostatically actuated and maintenance free. Actuator shall be of single piece, fail open design consisting of 1.2" diameter, welded 316L stainless plates capable
of releasing condensate within 5ºC (10ºF) of saturated pressure. Trap shall be constructed
entirely of 316L stainless steel components with wetted body surfaces finished to 20 µ inch
(0.5 µm) Ra or better. Trap shall be self draining when installed vertically in piping systems.
Trap shall have tube or universal hygienic clamps. Ferruled connections shall be Tri-clampcompatible and designed to fit both
1
/
2" and
3
/
4" service. Trap shall be guaranteed against defects
for 2 years.

SERVICE
NOTES
Trap is designed to be self draining for vertical installation (discharge down).
1
/2" - 3/4" ferrule service trap should be installed with 3/4" inlet gasket.
SLR ORIFICE
OPTION
Specify when immediate elimination of condensate and improved sensitivity is
desired. An orifice on the valve allows for continuous discharge of condensate.
Trap will nominally pass 50 lb/hr (22.7 kg/hr) of condensate at 50 psi (3.4 barg)
within 0.5ºC (1°F) of saturated temperature.
