THERMOSTATIC EXPANSION VALVES
PRODUCT DATA
Features
• TBE: with internal pressure equalisation; for single
injection in installations with one or more cooling
circuits.
• TBEX: 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
• Optional available with gas charge and MOP
• Adjustable superheat for two-way construction
• Fixed superheat setting for angle construction
• Warm thermal head provides best reliability
• Flare connections
• Extreme durable due to stainless steel head and
stainless steel diaphragm welded using protective gas
• Fixed orifice
• Refrigerants: R134a, R401A, R12
R22, R407C, R407A, R422D
R404A, R507A, R402A, R407B, R502

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

3. Gas charge
Refrigerants and MOP on request.
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 TBE series the thermal head is heated
advantageously by the liquid refrigerant. The warm thermal
head is on the safe side at any time.
