High quality
The TU is manufactured on fully automated,
process-monitored production lines.
Celluarized computer-monitored techno-
logy insures uniform high quality
and that when delivered, every valve meets
Danfoss quality standards and customer
specications. Celluarized production also
makes possible simultaneous production of
large and small quantities of standard and
custom version valves.
Benets of stainless steel
The fact that the TU is an all stainless
steel expansion valve oers a number of
benets:
· Stainless steel is far more corrosion
resistant than traditional valve
materials.
· Stainless steel valves require no
surface treatment.
· Stainless steel capillary tubes are
three times stronger and twenty
times more resistant to vibration than
copper capillary tubes.
· Stainless steel has a greater strength-
to-weight ratio, making TU valves
lighter and more compact.
· Stainless steel diaphragms have
greater strength and corrosion
resistance for longer life.
Danfoss precision port design
The TU thermostatic expansion valve
introduces Precision Port design
incorporating four features that insure
superior repeatable performance over an
extended valve life.
· Laser welding of the power element
preserves the structural uniformity of
the diaphragm, assuring consistent
operation.
· A precision-machined pushrod and
bushing make a practically frictionless
seal with no need for a packing gland.
· The free-oating push-rod is selfaligning
and eliminates binding.
· The precision-machined cone and orice
accurately meter refrigerant under all
operating conditions.
Advanced technology -
fast and easy installation
The new TU stainless steel thermostatic
expansion valve has signicant
installation advantages because it is a
valve designed specically for soldering.
The TU can be installed in less than half
the time required for traditional brass-
bodied valves.
The valve connections are made of
copper and stainless steel bi-metal
which makes installation easy, reliable,
and fast.
No need for a wet cloth...
Bi-metal has a very low thermal
conductivity, actually only 10% that
of copper, so heat applied during
soldering remains largely in the copper
layer of the connection tube, instead
of being conducted to the valve body.
External cooling is unnecessary.
The result is less energy consumption
and better solder quality. At the same
time, the diaphragm's structural
integrity is preserved.
