HVAC Element Thermostatic expansion valve TES 2 068Z3403 air
conditioning cold storage refrigeration accessories
The thermostatic expansion valve is used to adjust the supply
amount of the liquid refrigerant in the evaporator
The supply amount is controlled by the degree of superheat of the
refrigerant
This valve is therefore particularly suitable for the supply of
refrigerant liquid in a dry evaporator since the degree of
superheat of the refrigerant at the outlet of the dry evaporator is
proportional to the load of the evaporator
T2 and TE2 are typically replaceable flow port assemblies
For the same valve type and refrigerant, the matching flow port
assembly can be applied to all types of valve body and evaporation
temperature. The filling of the temperature sensing element depends
on the evaporation temperature range.
T2 (internal balanced expansion valve) and TE2 (external balanced
expansion valve) are available. A system with a dispenser must be
fitted with an external balanced expansion valve
Double contact temperature sensing package can quickly feel the
temperature changes within the evaporator, and easy to install.
T2, TE2-type expansion valve can withstand the impact of hot air
defrost
In order to extend the service life, all the spool and seat are
made of a special anti-wear alloy
Product Features:
◆ evaporation temperature range
◆ interchangeable flow port assembly
- Easier inventory
- Facilitates capacity matching
- Easier to repair
◆ refrigerant for the nominal R22 when the refrigerant is 0.5 ~
15.5kW
(0.15 to 4.5 TR)
◆ Valve with MOP function can be provided to prevent damage to the
compressor motor due to high evaporation pressure.
◆ Patented double contact temperature sensing package
- Quick and easy installation
- Good heat transfer between piping and temperature sensing package
◆ valve can provide a special temperature range
Technical Parameters:
◆ Maximum temperature
- Temperature after installation of the valve: 100 ° C
- Temperature package is not installed, the temperature of the
temperature package: 60O ℃
◆ The highest test pressure: 36bar
◆ Allowable working pressure: 28bar
Flow number and cold volume comparison table: the liquid
temperature before the valve is 41 ℃
