TH THW Thermal Expansion Valves
· Ttype expansion value is a novel thermostatic expansion value with replaceable valve element
· Ttype expansion value is used for adjusting the supply quantity of liquid refrigerant in evaporator
· Ttype expansion value is particularly suitable for supplying liquid refrigerant in dry-type evaporator
· Ttype expansion value has autocontrol through regulating thesuperheating degree of refrigerant.
