LIQUIDATOR 450
THERMOSTATIC TRAP
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.
Restricted orifice in UMT451T (small opening at bottom of
valve seat) prevents trap from discharging continuously on
light loads such as are encountered on tracer lines.

SPECIFICATIONS
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 will be available to allow condensate
evacuation at or near saturated temperatures. Where subcooling of
condensate is desired alternate thermostatic actuator will be available
to allow condensate evacuation at or near 40°F below 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 stainless steel bodied suitable for
pressures through 450 psig. Trap connection shall be two bolt
universal swivel mount. Mounting block shall be stainless steel and
available in 1⁄2" through 1" NPT or socket weld.

LIQUIDATOR UMT-TD
THERMODYNAMIC TRAP
Incoming air and condensate flow through the
trap body and into the Celtron® cartridge. Line
pressure raises the disc off the seat allowing
complete discharge. When flashing condensate
enters the cartridge, flow velocity increases,
creating low pressure underneath the disc.
Flashing condensate at high velocity strikes the
inside wall of the disc chamber and is
deflected to the top of the disc causing a pressure buildup.
The disc is forced down onto the seat by this pressure
imbalance. The trap remains closed as steam in the jacket
prevents exposure of the Celtron® cartridge to ambient
temperatures. Pressure inside the cap is not lowered until
the trapped flash vapor condenses. Condensing steam
lowers the pressure above the disc. Disc is then lifted and
the cycle repeated.

Improved Energy Savings — Lowers steam waste due to
steam jacketing. Trap cycle is unaffected by ambient
temperatures or precipitation.
Extended Trap Life — Integral strainer keeps disc and
seat clean. Non-violent discharge reduces wear. Heavy disc
prevents warpage and improves performance.
Easily Maintained — Completely renewable without
disturbing piping connections by removing cover,
unscrewing and replacing Celtron® cartridge. Celtron®
replacement cartridges are packaged individually with
cover and gaskets in a protective bag.
Freeze Proof — When mounted vertically or on its side
horizontally.
Multi-functional — Integral check valve eliminates need
for additional fittings.
Economical — First cost and maintenance cost are low.
