Series TMV
THERMOSTATIC EXPANSION VALVES
INTERCHANGEABLE ORIFICE CARTRIDGE
PRODUCT DATA
Features
• TMV / TMVBL: with internal pressure equalisation; for
single injection in installations with one or more
cooling circuits
• TMVX / TMVXBL: 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
TMVX 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
• Suitable for systems with hot gas defrosting
• Adjustable superheat setting
TMVXBL • Flare connections: TMV, TMVX
• Flare / solder connections: TMVBL, TMVXBL
• Extreme durable due to stainless steel head and
Application stainless steel diaphragm welded using protective gas
• Interchangeable orifice cartridges
Thermostatic expansion valves series TMV are used in
general refrigeration and for original equipment. • Refrigerants: R134a, R401A, R12
R22, R407C, R407A, R422D

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