DENSO A/C Expansion Valve - DVE21007

The air conditioning system in a vehicle cools or heats the the air blown into the passenger compartment, allowing a comfortable environmental level to be maintained and reducing the presence of humidity, dust and smells. The overall system generally consists of a heater, evaporator and a ventilation system including a blower, air ducts, and air purifier. These components are connected to each other with different tubes and hoses.

The role of a thermostatic Expansion Valve is to control the evaporation process in the evaporator. This process involves injecting the refrigerant into the evaporator, which changes the refrigerant from a high pressure and high temperature liquid into a low pressure and low temperature liquid and gas mixture. 

The Expansion Valve also adjusts the refrigerant quantity according to the temperature of the superheated gas at the evaporator outlet. This means that, as a result, conditions are maintained under which the change of the refrigerant state (evaporation) is completed and only gas will flow to the compressor.

Expansion Valves are an important component as they prevent potential freezing and blockage by reducing A/C outlet condensation. If the A/C system is not emitting cooled air, or only a little cool air, the expansion valve could be clogged or defective.

This A/C Expansion Valve - DVE21007 is part of DENSO's Thermal Systems range.
