Product Line Details: Expansion Valve

The Expansion Valve product line by Four Seasons focuses on delivering reliable A/C flow restrictors that regulate refrigerant flow within automotive air conditioning systems. The 39090 model is part of this line, engineered to provide consistent superheat control and maintain system efficiency in compatible vehicles like the Honda Prelude.

Technical Description and Features

This A/C expansion valve is made from brass, a material known for its corrosion resistance and durability under varying temperature conditions. It is designed for use with R134a refrigerant, the standard refrigerant type for many modern vehicles. The thermostatic expansion valve (Txv) design allows for precise modulation of refrigerant flow based on temperature changes, with a superheat setting of 4.5 to optimize cooling performance and prevent compressor damage.

Common Applications and Problem Solving

• Regulates refrigerant flow to maintain consistent cabin temperature
• Prevents compressor overheating by controlling superheat
• Addresses issues with uneven cooling or fluctuating A/C performance
• Helps reduce refrigerant leaks by maintaining proper system pressure
• Improves overall efficiency of the Honda Prelude air conditioning system

Installation Notes and Tips

When installing the Four Seasons Expansion Valve 39090 on a Honda Prelude, ensure the system is properly evacuated and free of contaminants before installation. Follow manufacturer torque specifications for fittings and verify the refrigerant type is R134a. Proper superheat adjustment is critical for optimal performance, so confirm the valve’s 4.5 superheat setting matches system requirements.

Quality Assurance and Warranty

Four Seasons Expansion Valve 39090 is manufactured to meet industry standards for durability and performance. The brass construction and Txv design contribute to long service life. Warranty details should be confirmed with the supplier or manufacturer, as coverage may vary.
