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 Further refrigerants on request.

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.

Installation
The valves may be installed in any position.
The external pressure equaliser line (TOEX) 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.
When tightening flare nuts of the flare connections grip at wrench flats on the valve body.
Do not bend or squeeze the bulb when tightening the bulb clamp!
Constructive modifications at the valve are not allowed.
Information for original equipment manufacturers:
The valve series TOE can be customised to the requirements of your series device in an optimum way. Contact us!
Superheat Adjustment (Two-way Valve
In general the Honeywell valves should be installed with the factory setting for the used refrigerant unaltered.
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. 0.25 bar. Increase of superheat setting results in a lower MOP-value and vice versa.
With TOEX angle construction there is no superheat setting in built-in condition possible, use factory setting.
