- Type T expansion valves are a new type of thermostatic expansion valve with replaceable cores.
- Type T expansion valves are used to regulate the supply of liquid refrigerant in the evaporator.
- Type T expansion valves are especially suitable for supplying liquid refrigerant in dry-type evaporators.
- Type T expansion valves perform automatic control by adjusting the superheat of the refrigerant.
