    HVAC Element Thermostatic expansion valve TEN 2 068Z3348 R134A for AC cold storage refrigeration accessories

    HVAC Element Thermostatic expansion valve TEN 2 068Z3348 R134A for AC 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 ℃
