THERMOSTATIC EXPANSION VALVES
PRODUCT DATA
Features
• TLE: with internal pressure equalisation; for single
injection in installations with one or more cooling
circuits.
• TLEX: with external pressure equalisation; for optimal
evaporation effectiveness in all applications.
Obligatory for multiple injection by liquid distributors.
• Combi adsorber charge as standard
The same valve can be used for different
refrigerants (see table on page 2)
Controller charge is high sensitive and responsive
thus lowest possible level of superheat can be
achieved
Charge is not sensitive to effects of temperature on
the capillary tube and valve head
damping characteristic results in stable control
behaviour
• Gas charge for deep freeze applications
• Adjustable superheat setting
• Warm thermal head provides best reliability
• Solder connections
• Extreme durable due to stainless steel head and
stainless steel diaphragm welded using protective gas
• Fixed orifice

Thermal systems with adsorber charge are completely
insensitive to effects of temperature on the capillary tube and
valve head. It reacts only according to the temperature of the
bulb.
Thus, Honeywell TLE and TLEX valves with combi adsorber
charge work absolutely reliable, even in icy condition or while
defrosting using hot gas.

With gas charged valves and MOP it is under all operating
conditions necessary that the bulb is always colder than the
capillary tube and the thermal head!
With the Honeywell TLE and TLEX series the thermal head is
heated advantageously by the liquid refrigerant. The warm
thermal head is on the safe side at any time.

Installation
• The valves may be installed in any position.
• The external pressure equaliser line (TLEX) should be
6 mm or 1/4" in diameter and is to be connected downstream of the remote bulb. An overbow is recommended in
order to prevent the ingress of oil into the equaliser line.
• The bulb should preferably be positioned on the upper half
of a horizontal suction line but never after a liquid trap. As
a general rule, bulbs of expansion valves should be
insulated to prevent them being affected by the ambient
temperature.
• When soldering the valve, the valve body must not get
warmer than 100 °C.
• Do not bend or squeeze the bulb when thightening the
bulb clamp!
• Constructive modifications at the valve are not allowed.
Information for original equipment manufacturers:
The valve series TLE can be customised to the
requirements of your series device in an optimum way.

Superheat Adjustment
In general the Honeywell valves should be installed with the
factory setting for the used refrigerant unaltered.
At combi adsorber valves the label on the capillary tube
indicates how to adjust the adjusting spindle (with arrow for
direction), depending on the refrigerant used. This correction
of the adjustment is essential to ensure that the control
performance of the valve is correct. The refrigerant used must
be marked on the label.
This superheat adjustment is calibrated for lowest
superheating and optimum evaporator utilisation. However,
should it be necessary to adjust the superheat, turn the
adjusting spindle as follows:
Turning clockwise
Turning
counterclockwise
One turn of adjusting spindle alters superheat setting by
approx. 0.25 bar. Increase of superheat setting results in a
lower MOP-value and vice versa.
