Honeywell TOE PRODUCT DATA
Series TOE
THERMOSTATIC EXPANSION VALVES FIXED ORIFICE, O-RING CONNECTIONS
TOEX 0.5 - 4.5 two-way
TOEX 0.5 - 4.5 angle
Application
Thermostatic expansion valves series TOE(X) are used in plants with one or more refrigerant circuits, especially for series installations, mobile air-conditioning and cooling units with O-ring connection, e. g. bus AC, train AC, transport cooling.
PRODUCT DATA
Features
•TOE: with internal pressure equalisation; for single injection in installations with one or more cooling circuits.
•TOEX: 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
•O-ring connections
•Extreme durable due to stainless steel head and stainless steel diaphragm welded using protective gas
•Fixed orifice
•Refrigerants: R134a
R22, R407C, R422D
R404A, R507A

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 TOE(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 TOE series the thermal head is heated advantageously by the liquid refrigerant. The warm thermal head is on the safe side at any time.
