Four Seasons 39440 A/C Block Type Expansion Valve without Solenoid

The Four Seasons 39440 is a block-type air conditioning expansion valve engineered to regulate refrigerant flow and maintain optimal cooling performance in automotive HVAC systems. This precision-calibrated valve controls the metering of high-pressure liquid refrigerant into the evaporator, creating the necessary pressure drop to lower refrigerant temperature for efficient cabin cooling.

Key Features:

• Block-type aluminum construction for corrosion resistance and durability
• Designed without solenoid for simplified operation and reliable performance
• Engineered to meet or exceed OEM fit, form, and function specifications
• Calibrated for proper tonnage, superheat, and maximum operating pressure (MOP)
• Compatible with R134a refrigerant systems
• O-ring type liquid inlet for leak-free connections
• 100% function tested prior to shipping for guaranteed quality

Four Seasons expansion valves are manufactured using advanced design software and precise measuring equipment to ensure each valve matches original equipment specifications. The aluminum block construction provides long-lasting durability while the internal components are designed to OE specifications for optimal refrigerant metering. This expansion valve helps prevent compressor damage, resolves inconsistent cabin cooling, and maintains proper A/C system efficiency.
