GPD 3411556 Block-Type A/C Expansion Valve Heavy-Duty Truck

The GPD 3411556 is a block-type A/C expansion valve engineered as a direct-fit aftermarket replacement for heavy-duty truck air conditioning systems. Rated at 1.5 tons, this valve features 1/2" inlet and 3/4" outlet port sizing (hose side) and is designed for use with R134a refrigerant systems.

The expansion valve regulates the flow of refrigerant into the evaporator core, metering the correct amount of refrigerant to maximize the A/C system's cooling efficiency. A properly functioning expansion valve prevents both flooding and starving of refrigerant supply to the evaporator.
