Thermostatic Expansion Valve TES2_R404A/507 068Z3403 (body without ORIFICE) screw-type with external equalizer DANFOSS

-40/+10°C / -40/+50°F — SS 4°C / 7.2°F — 3/8" × 1/2" Angleway Flare/Flare/Flare.

This valve must be equipped with an orifice according to the tonnage of your installation (please ask us!).

TE = EXTERNAL EQUALIZER.

The thermostatic expansion valve meters the refrigerant flow to the evaporator, using a thermal sensing element to detect and transmit the superheat. The valve opens or closes in response to the thermal element.

The thermostatic expansion valve maintains a constant superheat within the evaporator. Excessive superheat is undesirable, but a small amount is necessary with this type of valve to prevent liquid refrigerant from leaving the evaporator. Excessive pressure drop in the refrigeration circuit causes insufficient refrigerant supply to the evaporator by the valve. The use of a thermostatic expansion valve with an external equalizer compensates for the pressure drop across the evaporator. The external equalizer line is connected to the suction line after the sensing bulb of the expansion valve.
