Expansion Valve


ABOUT

ABOUT

Expansion valve causes rapid refrigerant expansion by injecting high-temperature, high-pressure liquid refrigerant through a small orifice, in effect creating a low-temperature, low-pressure mist refrigerant.

The expansion valve adjusts the refrigerant quantity according to the state of refrigerant vaporization in the evaporator. As a result, conditions are maintained under which liquid refrigerant takes heat from the surrounding air so that refrigerant is continuously evaporated at the evaporator outlet.


TYPES OFFERED

TYPES OFFERED

Joint Connection Type (C and ZFC Type)

Characteristics:

Requires the connection of a thermo-sensitive tube and equalizing pipe to the evaporator outlet.

 

Box Type

Characteristics:

Since refrigerant from the evaporator outlet flows through the box-type expansion valve, the expansion valve itself can internally detect refrigerant pressure and temperature.
