Refrigerator Air Conditioning Cold Storage T-shaped Right-angle External Balance R22/R404/134A Hongsen Expansion Valve
· T-type expansion valve is a novel thermostatic expansion valve with replaceable valve element
· T-type expansion valve is used for adjusting the supply quantity of liquid refrigerant in evaporator
· T-type expansion valve is particularly suitable for supplying liquid refrigerant in dry-type evaporator
· T-type expansion valve has autocontrol through regulating the-superheating degree of refrigerant.
·Large scope of evaporating temperature.
.be capable of providing MOP function so as not to damage the compressor motor due to overhigh evaporating pressure.
Have two forms of internal and external balance, be capable of removing influence brought loss of evaporator pressure effectively.
.Have the membrane structure with invention patent, greatly improve the working performance at low temperature.
. he bonnet adopts a secondary sealing structure to ensure zero external leakage.
· replaceable valve element component with 100-mesh filter has convenient storage, matching and
maintenance
The temperature wrap has mixed charging technology so as to have the feature of superheating degree within the whole evaporating temperature scope
· Capillary length of T-type thermostatic expansion valve:1.5m in atandard; under special situation,it can be customized based on clients' requirements.
