Technical Description and Specifications

This A/C expansion valve is crafted from aluminum, offering corrosion resistance and lightweight durability. It features a gold color finish and is designed for R134a refrigerant systems. The block-type valve includes two mounting holes for secure attachment. Both suction inlet and outlet fittings are female with No. 10 thread diameters, while liquid inlet and outlet fittings are female with No. 6 and No. 10 thread diameters respectively. The fittings use insert o-ring types with green o-rings included for proper sealing. The liquid inlet size measures 0.35 inches (9 mm), and the liquid outlet size is 0.65 inches (16.54 mm). This valve is engineered to meet or exceed OEM standards, ensuring compatibility and reliable operation in Hyundai Magentis, Sonata, and Kia Optima, XG300, and XG350 models.

Common Applications and Issues Addressed

• Regulates refrigerant flow to maintain optimal A/C system pressure
• Prevents compressor damage caused by improper refrigerant metering
• Resolves inconsistent cabin cooling or fluctuating air temperatures
• Eliminates issues related to refrigerant leaks at the expansion valve
• Supports efficient operation of R134a-based air conditioning systems

Installation Notes and Tips

Ensure the vehicle’s A/C system is fully evacuated and free of contaminants before installing the expansion valve. Use the two mounting holes to securely fasten the valve in place. Verify that all female fittings are properly seated with the included green o-rings to prevent leaks. Avoid cross-threading by aligning fittings carefully, as the suction and liquid fittings are not threaded but rely on insert o-ring seals. After installation, recharge the system with R134a refrigerant and test for proper operation.
