Series TMVL
THERMOSTATIC EXPANSION VALVES
INTERCHANGEABLE ORIFICE CARTRIDGE, SEPARATE SOLDER BASE
PRODUCT DATA
Features
• Only one valve body necessary for internal and
external pressure equalisation. Connection for
pressure coupler is integrated in the solder base.
• TMVL: Valve body and solder base with internal
pressure equalisation; for single injection in
installations with one or more cooling circuits.
• TMVLX:Valve body and solder base with external
pressure equalisation; for optimal evaporation
effectiveness in all applications. Obligatory for
multiple injection by liquid distributors.
• Combi adsorber charge
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
TMVLX-W
TMVLX-D
Application
Thermostatic expansion valves series TMVL are used in
general refrigeration and for original equipment.
Plants with one or more refrigerant circuits such as
refrigerated cabinets even with cramped mounting conditions,
ice and cream machines, milk cooling systems, cold stores,
air conditioning systems and heat pumps.

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 TMVL valves with combi adsorber charge
work absolutely reliable, even in icy condition or while
defrosting using hot gas.

Installation
• The valves may be installed in any position.
• The external pressure equaliser line 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.
• Do not bend or squeeze the bulb when tightening the bulb
clamp
• The screws fixing the valve body to the solder base must
be tightened in diagonal sequence (torque 12 Nm).
• Constructive modifications at the valve are not allowed.
• Never quench the solder base with water after soldering,
this may cause cracks and distort the sealing surfaces.
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. 0.55 bar. Increase of superheat setting results in a
lower MOP-value and vice versa.
