Honeywell TMVL PRODUCT DATA

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.
