Autopart International 2403-508309 A/C Expansion Valve

The Autopart International 2403-508309 is an automotive air conditioning expansion valve designed to regulate refrigerant flow within the A/C system. This component serves as a critical metering device that controls the amount of refrigerant entering the evaporator core.

Key Functions:

• Regulates refrigerant pressure and flow rate from the high-pressure liquid line to the low-pressure evaporator
• Converts high-pressure liquid refrigerant into a low-pressure mist for optimal cooling performance
• Maintains proper superheat levels to prevent liquid refrigerant from entering the compressor
• Helps optimize A/C system efficiency and cooling capacity

This replacement expansion valve is manufactured by Autopart International to meet or exceed original equipment specifications. The valve installs between the receiver-drier and evaporator in most automotive A/C systems, providing reliable temperature regulation and system protection.
