Four Seasons 39634 A/C Expansion Valve

The Four Seasons 39634 A/C expansion valve is a precision-engineered component designed to regulate refrigerant flow in automotive air conditioning systems. This thermostatic expansion valve (TXV) is specifically calibrated to provide proper refrigerant flow to the evaporator while restricting high-pressure liquid, causing a pressure drop that lowers refrigerant temperature for optimal cooling performance.

Key Features:

• Engineered to meet or exceed OE fit, form, and function requirements
• Precision-calibrated for specific tonnage, superheat, and maximum operating pressure (MOP)
• High-quality components ensure long-lasting performance and reliability
• Tested, validated, and inspected by engineers with over 45 years of automotive A/C experience
• Manufactured by the industry's largest aftermarket climate control parts supplier

Four Seasons expansion valves are critical components for maintaining proper air conditioning system performance. Misapplied or low-quality valves can lead to A/C performance issues, making it essential to choose a properly specified replacement component from a trusted manufacturer.
