TH THW Thermal Expansion Valves For Refrigeration / Air Conditioning System, Evaporator,Condensing Unit Used
Description:
1. T-type expansion value is a novel thermostatic expansion value with replaceable valve element
2. T-type expansion value is used for adjusting the supply quantity of liquid refrigerant in evaporator
3. T-type expansion value is particularly suitable for supplying liquid refrigerant in dry-type evaporator
4. T-type expansion value has autocontrol through regulating the-superheating degree of refrigerant.
