SK200-8 Air Conditioner Expansion Valve YN20M00107S021 for KOBELCO Excavator | OEM A/C Expansion Valve
Product Overview | A/C Expansion Valve YN20M00107S021
The YN20M00107S021 air conditioner expansion valve is a critical component in the KOBELCO SK200-8 HVAC system. Positioned at item 27-1X in the air conditioning assembly diagram, this valve controls the flow of refrigerant entering the evaporator, maintaining proper pressure and temperature for optimal cooling performance.
A faulty expansion valve commonly causes evaporator freeze-up — a frequent complaint among SK200-8 operators where the A/C blows cold briefly then loses airflow. Replacing the expansion valve restores proper refrigerant regulation and consistent cabin cooling.

Symptoms of a Failing Expansion Valve
-
Evaporator freeze-up — A/C blows cold then air stops flowing
-
Insufficient cooling — Cabin not reaching comfortable temperature
-
Frost on evaporator lines — Ice buildup on refrigerant lines
-
Compressor cycling rapidly — Pressure imbalance in system
If your KOBELCO SK200-8 exhibits these symptoms, the expansion valve is the most likely culprit.

FAQ | SK200-8 Air Conditioner Expansion Valve
Q1: What does the YN20M00107S021 expansion valve do?
A: It regulates refrigerant flow into the evaporator, controlling pressure and temperature to ensure efficient cabin cooling and prevent evaporator freeze-up.
Q2: How do I know if my SK200-8 expansion valve is bad?
A: Common signs include A/C blowing cold then losing airflow (freeze-up), insufficient cooling, and frost on refrigerant lines. If the evaporator freezes, the expansion valve is the primary suspect.
Q3: Is YN20M00107S021 compatible with other KOBELCO models?
A: Yes. This valve fits SK200-8, SK210-8, SK250-8, SK260-8, and SK210LC-8. It is also compatible with several New Holland excavator models including E135BSR, E150BSR, E215B, E235BSR, and E485B.
Q4: Do I need to replace other A/C components at the same time?
A: If the system has been contaminated by a failed compressor, we recommend flushing the system and replacing the receiver drier and expansion valve together. For a simple valve failure, replacing the valve alone is sufficient.
Q5: What warranty do you offer?
A: We offer a standard warranty on this expansion valve. Contact us for specific terms based on your location.
