Detailed Description

This Global Parts A/C expansion valve, part number 3411278, is used in HVAC systems where precise refrigerant metering is required. By slowing refrigerant before it reaches the evaporator, the valve helps the system make better use of cooling capacity. It is listed for a wide range of Mercedes-Benz models, including the 1994-2003 Mercedes-Benz C220, C230, C280, C36 AMG, C43 AMG, CLK320, CLK430, CLK55 AMG, E300, E320, E420, E430, E55 AMG, S420, SLK230, SLK320, CL500, and CL600, plus 1985-1989 BMW 635CSi. If you are servicing a Mercedes-Benz E320 or CLK430 A/C system, 3411278 is a direct part number to verify against the original component.

What It Helps Address

  • Weak or uneven cabin cooling
  • Incorrect refrigerant metering at the evaporator
  • A/C performance loss after system service
  • Expansion valve wear in older Mercedes-Benz HVAC systems
  • Restoration work on Mercedes-Benz E320, C280, and CLK320 A/C systems

Installation Notes and Tips

Replace the expansion valve/orifice tube during A/C service as recommended by the manufacturer. Verify the original part number, refrigerant system design, and O-ring compatibility before installation. Clean the system thoroughly and confirm proper evacuation and recharge procedures after service.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced, reflecting its role as a wear-related service component in the refrigerant circuit. Confirm fitment by year, make, model, and original part number before ordering.
