Nothing kills productivity on long windrowing days like an A/C system that won’t keep you cool. Whether your cab’s getting too hot, the air’s blowing inconsistently, or you’re seeing ice buildup on your evaporator, a faulty expansion valve is often the culprit. This replacement valve controls exactly how much refrigerant flows to your evaporator, making the difference between sweltering through harvest and staying comfortable all day long.
Key Features
- Bulb-type sensing element responds instantly to temperature changes for precise control
- O-ring seal design prevents refrigerant leaks and keeps your system charged properly
- Externally equalized design ensures accurate pressure sensing for optimal performance
- 28-inch capillary tube allows flexible mounting and proper bulb placement
- Compatible with both R12 and R134a refrigerants – works with older and converted systems
Built for Real Farm Work
This valve is designed for windrower applications where operators spend long hours in dusty, demanding conditions. Whether you’re cutting alfalfa in the heat of summer or pushing through heavy windrows, your A/C needs to work reliably. The external equalization feature ensures the valve responds accurately to system conditions even when your machine is working hard.
Made to Last
Farm A/C components face extreme temperature swings, vibration, and contamination that would kill automotive parts. This expansion valve uses robust construction and quality materials that handle the punishment of agricultural use. The sealed design keeps moisture and debris out while maintaining precise refrigerant control season after season.
Installation Notes
A/C work requires proper equipment and EPA certification, so this job is best left to a qualified technician. The sensing bulb needs to be clamped tightly to the evaporator outlet line for accurate temperature readings. Always replace the receiver-drier when changing expansion valves to remove any moisture or contamination that could cause premature failure.
