Thermal actuator is filled at it’s free length with a
liquid having a lower boiling point than water. As
assembled, valve is normally open. On startup, air
passes through vent.As air is eliminated, hot steam
reaches vent and the thermal actuator fill vaporizes
to a pressure higher than line pressure. This forces

valve into seat orifice to prevent any further flow. Should
more air collect, it takes heat from the actuator, lowering
internal pressure. Line pressure will then compress thermal
actuator to open valve and discharge air. Valve lift auto­matically adjusts to variations.

THERMOSTATIC STEAM

TRAPS

Pressures To 100 PSIG (6.9 barg)

Temperatures to 338°F (170°C)

Stainless Steel Body—Body materials 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—One moving part.

Inconel welded actuator for maximum corrosion, thermal
and hydraulic shock resistance.

Thermal and Hydraulic Shock Resistant—Impingement

plate plus welded construction prevents damage to actuator.

Valve and Seat—Long life, stainless steel valve and seat

lapped and matched together for water tight seal.

Maintenance—All models are sealed and maintenance free.
Three Year Guarantee—Trap guaranteed for three years

against defects in material or workmanship.

Additional Features—Best air handling capability for fast

start up and operation. Fastest response to condensate
load or temperature changes. Broad application range.
Selection of orifice and pipe sizes meet majority of conden­sate removal demands in deionized steam systems.

Unique 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 k g /h r ) o f condensate at 50 psi (3.4 barg) within 0.5ºC
(1°F) of saturated temperature.

Connections:

3/8" – 3/4" NPT or socketweld

Steam trap shall be of balanced pressure design with 316L welded bellows
capable of releasing condensate within 5ºC (10°F) of saturated pressure. Where
drainage at saturated temperatures is required, trap shall have SLR orifice. All
other components shall be of 316 or 316L stainless steel. Trap shall be self
draining and normally open.

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 saturat-
ed temperature.
