Product Details

The expansion valve is a critical A/C flow restrictor that controls refrigerant delivery into the evaporator. By slowing refrigerant before it enters the evaporator, the system can better manage cooling performance and maintain proper refrigerant metering. Global Parts 3411374 is specified as an Exp Valve 16mm x 22mm Int Eq 14in and is listed for Land Rover Discovery and Range Rover HVAC service applications.

This part cross-references UAC EX10128C for the same application.

What It Helps Address

• Weak or inconsistent cabin cooling
• Improper refrigerant metering at the evaporator
• A/C performance loss after system service
• Restricted refrigerant flow caused by a worn valve
• HVAC service needs on Land Rover Discovery and Range Rover models

Installation Notes and Tips

Replace the expansion valve during A/C service when the system is opened, especially after compressor, evaporator, or line repairs. Verify the 16mm x 22mm internal equalization configuration before installation and confirm the vehicle application against the listed fitment for 1999-2004 Land Rover Discovery and 1990-1994 Land Rover Range Rover. Proper evacuation, leak checking, and refrigerant recharge are required after installation.

Quality Assurance

Global Parts supplies this HVAC component as a service replacement part for Land Rover A/C systems. The manufacturer recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain proper refrigerant control.
