Four Seasons A/C Expansion Valve P/N:38814

Restore precise refrigerant metering to your air conditioning system with the Four Seasons Block Type A/C Expansion Valve, MPN 38814. This aluminum block-type valve drops in across a broad list of applications, including the 2000 Chevrolet Astra and a wide range of Mercedes-Benz models such as the 1994-1997 C220, 1996-2002 E320, and 1998-2002 CLK320 — see the Buyer's Guide tab for the full list of 19 applications.

• Block-type design, without solenoid: a compact H-block valve that mounts between the evaporator and the liquid and suction lines.
• Aluminum construction with precision-machined ports for clean, accurate sealing surfaces.
• Calibrated for R134A: rated at 2.0 tons with a 7.0 superheat setting for controlled cabin cooling.
• Includes application-specific O-rings (24606, 24608, 24610, 24612) to complete the replacement.
• Meets or exceeds OEM fit, form, and function requirements.

As a block-type expansion valve, it controls the flow of liquid refrigerant into the evaporator based on system superheat, helping regulate the cooling cycle. If a stuck or failed expansion valve is the cause of weak or inconsistent A/C performance, this valve replaces it. Mounting hardware is not included. Manufacturer part number 38814.
