Global Parts 3411577 A/C Expansion Valve

BMW A/C Expansion Valve for Precise Refrigerant Control

Global Parts 3411577 is an A/C expansion valve for BMW HVAC systems. It meters refrigerant flow before the evaporator so the system can use cooling capacity efficiently, helping restore stable cabin air conditioning performance.

Key Features

• Expansion valve/orifice tube style A/C flow restrictor
• Controls refrigerant delivery to the evaporator
• Built for BMW 2 Series, 3 Series, 4 Series, M models, and select 5 Series applications
• Direct replacement for service and repair work on the A/C system
• Part number 3411577 for easy identification

Detailed Description

This Global Parts A/C expansion valve is used in BMW air conditioning systems to regulate refrigerant entering the evaporator. By slowing refrigerant flow at the correct point in the circuit, it helps the evaporator absorb heat more effectively and supports consistent vent temperatures. This part number 3411577 also cross-references UAC EX10448C for the same application.

• Incorrect evaporator refrigerant metering
• A/C performance loss after system service
• Temperature fluctuations from the vents
• Restricted refrigerant flow in the HVAC circuit

Installation Notes and Tips

Replace the expansion valve during A/C service when the system is opened. Verify the vehicle application by year, model, and position before installation. Clean the system thoroughly and follow BMW service procedures to protect the compressor, evaporator, and refrigerant circuit.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain proper refrigerant control and cooling performance.
