The Expansion valve and orifice tube serves as a key component in the vehicle's HVAC system, controlling the flow of refrigerant to maintain optimal cooling performance. This part is commonly used in vehicles equipped with air conditioning systems. With its precise control over refrigerant flow rates, the
MAHLE AVE81000P expansion valve enhances efficiency and reliability.
AC expansion valves regulate refrigerant flow from the high-pressure liquid line to the evaporator core in vehicle air conditioning systems. These valves meter refrigerant based on evaporator superheat, ensuring optimal cooling performance and preventing liquid slugging. Common designs include thermal expansion (TXV) valves, utilizing a sensing bulb and capillary tube, and electronically controlled valves with stepper motors for precise adjustment. Operation relies on a pressure differential across the valve, controlled by temperature or electronic signals. Materials typically include corrosion-resistant brass, steel, or aluminum alloys, and valve orifice size is critical for system compatibility.
