2. ALCO type TI & TIE
3. Sporlan type FVE & SVE
4. New Type SNRF
4. New Type SNRF
Thermostatic expansion valve regulate the flow rate of refrigerant intoevaporators according to its degree of superheat.Both the internal equalizer andexternal equalizer systems are furnished,especially, the external equalizertype, used for central air conditioning, commercial refrigeration andtransportation A/C and refrigeration.
Wide range of evaporator temperature: -40°C~+10°C
